Fedora 16 bugzilla status report from 2012-02-03 to 2012-02-10

Fedora 16 is currently shipping 3.2.3, the latest stable kernel.
We currently have 472 bugs open against it.

In the last week, we closed out 63 bugs, and saw changes to 91 bugs that are still open.

Interesting closures:
Looking over the list, a lot of duplicates jump out. Many of these were filed by different people, but in some cases, abrt is just being dumb.

Most commonly reported bugs in the last week:
768639: [abrt] kernel: WARNING: at /builddir/build/BUILD/kernel-3.2.fc16/compat-wireless-3.3-rc1-2/drivers/net/wireless/ath/ath9k/rc.c:697 ath_rc_get_highest_rix+0×158/0x1f0 [ath9k]()

784692: hso: WARNING: at net/sched/sch_generic.c:255 dev_watchdog+0×247/0×250()
Another bunch of reports from the net/sched/sch_generic WARN_ON where the transmit queue locks up.
possibly related: 785806: e1000e Detected Hardware Unit Hang

Looking at the 26 closed bugs that weren’t duplicates, there’s a few wireless bugs that got fixed in an update, a handful of things that turned out to be bad hardware or user misconceptions, and generally pretty boring stuff.

The list of still open bugs is more interesting, especially from a ‘pattern spotting’ perspective.

We get a ton of wireless bug reports these days.
It seems like we get a lot more since we switched to using compat-wireless snapshots.

There are a number of bugs that look all related, that take the form “irq happened, nobody cared”. Many of these seem to be using the ASM108x chipset.
Searching for irqpoll turns up a lot of these
There’s some work going on upstream to fall back to polling automatically. We’ll pick this up and backport it.

787533: WARNING: at drivers/usb/host/ehci-hcd.c:1178 ehci_endpoint_reset+0xee/0×100()
This last one is interesting. We also saw this on F15.
From discussion with Alan Stern upstream, this appears to be hplip doing something wrong, and always trying to clear halt status on an endpoint, even if it hasn’t been set.

754518: oops in sd_revalidate_disk
SCSI patch goes unapplied upstream. Film at 11. The number of hotplug related crashes in SCSI continues to amaze. Things really started going to shit after circa 2.6.37

Soft lockups.
789002: BUG: soft lockup – CPU#0 stuck for 23s! [kworker/u:0:2600]
Looks like the ath9k chip locked up, and the ioread never completed. Nasty.

788279: BUG: soft lockup – CPU#3 stuck for 23s! [flush-254:0:1124]
IO related stalls.
788938: BUG: soft lockup – CPU#3 stuck for 22s! [systemd-stdout-:563]
This one is weird. Systemd tried to open something, it blocked for 22 seconds.
788620: BUG: soft lockup – CPU#1 stuck for 30s! [kworker/1:1:9884]
atl1c locked up while checking link status. This seems to be a common thing for network drivers.

759063: WARNING: at net/ipv4/tcp.c:1485 tcp_recvmsg+0x1bb/0x7f1()
Back traces and warnings from the network layer always give me the creeps.
Not entirely sure what’s happening here yet, or even if it’s reproducable.

Totally weird shit:
