Hello LKML,
I hope this is the right place for this sort of bug report: if there's a
better place, please do point me there.
[1.] Oops and panic on disconnecting Edirol UA-1000 usb2 audio interface
[2.] I have an Edirol UA-1000 USB 2.0 Audio Capture unit. When
disconnected (or powered down), it repeatably causes a kernel panic, in
(I think) linux/drivers/usb/host/ehci-q.c, start_unlink_async(), around
line 1015:
while (prev->qh_next.qh != qh)
prev = prev->qh_next.qh;
where somehow prev->qh_next.qh==NULL.
[3.] usb2 ehci edirol ua-1000 unplug oops panic
[4.] kernels 2.6.12, 2.6.12-rc4, 2.6.12-rc3, 2.6.12-rc2-mm3,
2.6.11.8, 2.6.11-ac7, and some older kernel.org kernels besides. The
SuSE 9.1-supplied 2.6.5 kernels don't oops or panic, but also don't
recognise the UA-1000 as an audio device at all.
[5.]
Oops: 0000 [#1]

<0>Kernel panic - not syncing: Fatal exception in interrupt
[6.] I don't know if there's any other USB hardware can cause this; it's
100% reproducible for me with the UA-1000.
[7.1.] ver_linux.txt
[7.2.] cpuinfo.txt
[7.3.] modules.txt
[7.4.] lspci.txt
[X.] The same thing seems to happen without CONFIG_PREEMPT and without
CONFIG_SMP, too. Also it happens both with the laptop's built-in USB 2
ports and with a Belkin PCMCIA USB 2 card.
I hope this report makes sense. I'm still only a few steps on from being
a Linux beginner, but I'm happy to try out patches, fiddle with my
.config, or whatever it takes to get to the bottom of this.
Colin Fletcher.
