Hi,

This looks like a memory fault to me; are those 0x6b characters "slab poisoning"? This is the dual
P4 Xeon / 2 GB RAM machine, and I'm guessing that udevd has just loaded snd_rtctimer (because
that's the module at the top of the list):

Yes, from include/linux/poison.h:
#define POISON_FREE	0x6b	/* for use-after-free poisoning */

Do you have any of the preceding kernel log messages?
or can you get them?


Anyone:  in sound/core/rtctimer.c::rtctimer_init(), does
this code:

	tasklet_init(&rtc_tasklet, rtctimer_tasklet, (unsigned long)timer);

	/* set up RTC callback */
	rtc_task.func = rtctimer_interrupt;
	rtc_task.private_data = &rtc_tasklet;

	err = snd_timer_global_register(timer);
	if (err < 0) {
		snd_timer_global_free(timer);
		return err;
	}

need to call tasklet_kill(&rtc_tasklet);
before the return err; ??

snd_timer_global_register() itself doesn't issue any tasklet, so it
shouldn't be needed.

snd_timer_global_register() itself doesn't issue any tasklet, so it
shouldn't be needed.

Unfortunately, there was none. I posted everything there was. Race condition, perhaps?

Hmm, this bug looks interesting:

Yes, my machine *is* a dual P4 with HT enabled...

So udevd is closing a sysfs attribute file but the pointer passed to
module_put is bogus. Looks like the sysfs dentry was already taken
down by release_sysfs_dirent(). Can you reproduce this at will? Does
the oops happen in older kernels?

Yeah, but the oops looks more like a reference counting problem with
sysfs dentries. No harm in trying out the patch or reproducing without
CONFIG_SCHED_SMT though.

Yeah, but the oops looks more like a reference counting problem with
sysfs dentries. No harm in trying out the patch or reproducing without
CONFIG_SCHED_SMT though.

No, unfortunately I can't. Last night was the first time this ever happened (while I was starting
up World of Warcraft/Wine), so I have no idea which sysfs attribute it is talking about here.

Nope, no difference. Again, this happened while trying to start World of Warcraft. However, this
time there is no snd-rtctimer module in the stack.

Please apply this patch to your kernel and try to reproduce:

http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.20/2.6.20-mm2/broken-out/gregkh-driver-sysfs-crash-debugging.patch

It should give us a better clue which sysfs file is causing the oops.

I think that eth1 and eth2 are both "eth1394" devices, automatically loaded on the two Firewire
"hubs"(?) in this machine?
