You can put it in /etc/portage/patches/sys-kernel/gentoo-sources/ If that does not fix it, we might want to file this upstream (under Drivers -> Network) at https://bugzilla.kernel.org
Thanks Tom, will try as soon as I can. Meanwhile, two updates: 1. Has now happened on a different AP (BT Business Hub) 2. May also be causing panics: I've had a few, but not (thus far) while rt2800pci is blacklisted.
Patched; no change I'm afraid. Anecdotally, it took longer than before (about 30min) to fail, but I wasn't making as much traffic during that time, so in bytes-transmitted-before-failure terms, might be about the same.
Still occurring on 3.11.1. The panics I mentioned appear to be unrelated, as they've now happened with rt2800pci blacklisted. I was about to test some of the 3.10.* iterations I'd skipped, to check if the issue appeared earlier, then realised I'd cleverly unmerged 3.10.0 including its .config, so I may have a problem there. Is there any way of doing a "reverse make oldconfig" using my 3.11.0 config? I've turned on all debugging I can, so more output (hopefully) to follow.
OK, a kernel bug[1] (regression caused by adding MSI support) has materialised in the meantime, and its patch[2] is working pretty good so far here. Been up about an hour, sustained throughput, no dropouts, and only one missed-beacon message in the log. Looks good! [1] https://bugzilla.kernel.org/show_bug.cgi?id=61621 [2] http://marc.info/?l=linux-wireless&m=137992749815360&w=2
Spoke too soon. I went and visited the other aforementioned AP for a bit of torture-testing, and after an hour or so got kicked with similar output. The patch definitely helps a lot, and it's possible the signal just isn't good enough there -- my ar5523 backup dongle doesn't work at all there, and the rt3290 had been known to drop-out occasionally there too -- but I definitely see a decline, and (although maybe I just wasn't patient enough) it seemed to need reloading the rt2800pci module before it could reconnect. With the improvement, my focus returns to catching up on actually using the machine, but I'm still ready to help debug as directed, just let me know.
I believe this might be addressed with: http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/net/wireless/rt2x00/rt2x00pci.c?id=dfb6b7c109a7f98d324a759599d1b4616f02c79f Which is in vanilla 3.12.0 and gentoo-sources-3.12.0. Can you test with that, please.
Yup, that's the patch I mentioned in comment #5. Thanks for the heads-up, will upgrade as soon as time allows. As per comment #6 there is still a minor issue of similar character, but certainly the situation has much improved.
OK, so 3.12.0 gets us better than unpatched 3.11.*, but still poorer than 3.10.* and, on early impressions, worse still than patched 3.11.*. Commentary on the kernel bug seems to agree with this assessment. Not sure where to look now, maybe something higher-level?
Any changes with the latest kernel at this time?
(In reply to Mike Pagano from comment #10) > Any changes with the latest kernel at this time? A bit hard to answer at home, because upgrading to gentoo-sources-3.13.0-r1 coincided with replacing my router with an 802.11n model, so there was an improvement but I attributed it to that. That said, the "Queue X failed to flush" message floods have dried up. Reviewing the logs, I do still see those messages on occasion, but I can identify those as times I was on the public AP mentioned above, and only when I was positioned farther away from the AP (where dropouts did occasionally occur even on 3.10.* and below), and they were much fewer in number (two bursts of half-a-dozen messages each, ~20 minutes apart). Anecdotally, I didn't get a dropout at that location, although I was experiencing some veeeery long web page load times/timeouts (a few minutes). Could be issues with the AP's WAN connection, of course. With some caution, I'd say we are back in pre-3.11 levels of performance/reliability. Were there any particularly significant changes to the driver in 3.13? Nothing mentioned on the upstream bug.
Not that I'm aware of, but thanks for responding. Please feel free to comment you are still having issues.
