[ 426.246318] xhci_hcd 0000:00:14.0: Can't reset device (slot ID 4) in default state [ 426.246322] xhci_hcd 0000:00:14.0: Not freeing device rings Not sure if this helps? Does the device work on USB 2. Apparently there are some issues with xhci memory leaks. http://linux-usb.vger.kernel.narkive.com/SiQeYEDB/patch-1-2-xhci-fix-memory… Here's a snippet from that thread. Unfortunately, the original code in xhci_free_or_cache_endpoint_ring() would put the first entry into the ring cache in array index 1, instead of array index 0. This was caused by the second assignment to rings_cached: rings_cached = virt_dev >num_rings_cached; if (rings_cached < XHCI_MAX_RINGS_CACHED) { virt_dev->num_rings_cached++; rings_cached = virt_dev->num_rings_cached; virt_dev->ring_cache[rings_cached] = virt_dev->eps[ep_index].ring; This meant that when the device was freed, cached rings with indexes 0 to N would be freed, and the last cached ring in index N+1 would not be freed. When the driver was unloaded, this caused interesting messages like: xhci_hcd 0000:06:00.0: dma_pool_destroy xHCI ring segments, ffff880063040000 busy > > I do not yet have anything easy/constructive to add and I promise to > only reply if I do :) > > Andre > --- > Talk Mailing List > talk(a)gtalug.org > https://gtalug.org/mailman/listinfo/talk Russell Sent from mobile.

gmane.org gone, at least for now
by D. Hugh Redelmeier 31 Jul '16

31 Jul '16

gmane is an archive of all sorts of mailing lists / news groups. It made threads visible on the web. <https://lars.ingebrigtsen.no/2016/07/28/the-end-of-gmane/> This blog entry by the guy who ran it explains why it is down. I have several browser tabs that are now 404s. The wayback machine will work in a pinch: give it a gmane URL and a date and it should find the content. Here's the only one that I've tried: <https://web.archive.org/web/20150727001119/http://comments.gmane.org/gmane.…> BTW, this link is to discussion of a problem that I'm having. My Fujitsu Scansnap ix500 won't work when plugged into a USB 3 port on Linux. Very odd. This report is two years old and the problem persists.

Towards the end of Arcnet's tenure, we had become so tired of the flakiness that we had soldered the twisted pair to all the network cards. If you wanted to move a machine, you unplugged the arcnet card and left it hanging at the desk.

Hints for upgrading
by William Park 28 Jul '16

28 Jul '16

I just upgraded from Slackware-14.1 to 14.2. That's almost 3 years in between. :-) Here are what I did or have... 1. Single root filesystem /dev/sda1. For boot drive, you need MBR, but you can lump everything into one partition. When upgrading, - before "install", move all the old directories into /.old - during "install", don't partition or format /dev/sda (obviously) - after "install", copy files from /.old/etc to /etc, file by file but only when necessary (more later). 2. For non-boot harddisks, use the entire harddisk without partition, like /dev/sdb instead of /dev/sdb1. Yes, you can format EXT4 or BTRFS on the whole disk. 3. You can't just copy blindly from /.old/etc to /etc, because formats may be different, new options may be introduced, etc. - obviously, if files are the same, don't copy. cd /.old/etc find . -type f | while read f; do diff -q $f /etc/$f && echo $f; done find . -type f | while read f; do diff -q $f /etc/$f && rm $f; done - after that, diff and merge into /etc manually, file by file, vimdiff X /etc/X 4. If you plan to move the harddisk to another machine (like I do), then use MBR. Problem with EFI is that it writes the boot entry in BIOS. Well, on a new motherboard, boot entry is not there, so you can't boot. You have to dig into EFI shell, and manually select your .efi. -- William

The presentation will then be followed by an interactive session to discuss philosophical questions surrounding disruption, the meaning of "success" in the context of FOSS projects and whether "killer applications" for such projects are important. ## Location George Vari Engineering and Computing Centre 245 Church Street, Room 203 Ryerson University <http://goo.gl/maps/16oJ2> <http://www.openstreetmap.org/way/23447525> ## Schedule * 6:00 pm - Please discuss on the general mailing list (i.e. <talk(a)gtalug.org>) where you want to go for dinner. * 7:30 pm - Meeting and presentation. * 9:00 pm - After each meeting a group of GTALUGers move to the The Imperial Pub (54 Dundas St East) for refreshments and more socializing. # Code of Conduct We want a productive happy community that can welcome new ideas, improve every process every year, and foster collaboration between individuals with differing needs, interests and skills.

Ok just kidding, someone did once post a Windows crack on this list, the post was deleted and that issue was part of the formulation of the code of conduct. > <snip the middle> > > > pirates? with ships? one eyed Jack?

This was the interesting thing about Stuxnet, although it was Windows malware, it seemed to be able to transcend the OS in order to find its target. <snip the middle> > this openness to sometimes diverge from standard Linux topics also > strengthens the community as we get to know each other, learn from each > other and for me personally, to make me a better person :) The debate seems to be mostly about time. The time it takes to craft a reasonable response vs the time it takes to understand a response. And constructive criticism, how that criticism is presented and how it is perceived. I think Hugh hit the nail right on the head in his rebranded post's analysis of this thread. People's feelings get hurt when contents are construed incorrectly. Posting, according to first order reliability method, should have logical rules so that information remains true. I learned FORM as SAP under SOP while taking training in typesetting A single misplaced orthographic character in a printed form can radically alter the meaning of the contents. In cyberspace ... well you can read Hugh's analysis to see the iterative quality of compounded error. > > > > > > > > cheers, > > > Stewart > > > --- > > > Talk Mailing List > > > talk(a)gtalug.org > > > https://gtalug.org/mailman/listinfo/talk > > > > Sent from mobile. > > --- > Talk Mailing List > talk(a)gtalug.org > https://gtalug.org/mailman/listinfo/talk Sent from mobile.

2 weeks on cell phone and chromebook... never again!

I just spent 2 weeks living purely on cell phone (LG Nexus 5X) and chromebook (HP Chromebook 11 G3). Now, I'm back on real computer with real keyboard/mouse. What a difference in productivity! -- William
