Yes, from include/linux/poison.h:

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(_tasklet, rtctimer_tasklet, (unsigned long)timer);
/* set up RTC callback */
rtc_task.func = rtctimer_interrupt;
rtc_task.private_data = _tasklet;
err = snd_timer_global_register(timer);
if (err < 0) {
snd_timer_global_free(timer);
return err;
}
need to call tasklet_kill(_tasklet);
before the return err; ??

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

[BUG] Linux 2.6.20.1 - unable to handle kernel paging request - accessing freed memory?
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): BUG: unable to handle kernel paging request at virtual address 6b6b6ceb printing eip: c013010b *pde = Oops: 0002 [#1] PREEMPT SMP Modules linked in: snd_rtctimer radeon drm pwc eeprom cpufreq_ondemand p4_clockmod speedstep_lib nfsd exportfs ipv6 autofs4 nfs lockd sunrpc af_packet firmware_class binfmt_misc video thermal processor fan button ac lp parport_pc parport nvram video1394 raw1394 eth1394 compat_ioctl32 videodev snd_usb_audio sd_mod snd_usb_lib v4l2_common sg v4l1_compat snd_emu10k1_synth snd_emux_synth snd_seq_virmidi snd_seq_midi_emul snd_emu10k1 snd_rawmidi snd_ac97_codec ac97_bus snd_seq_dummy snd_seq_oss ohci1394 snd_seq_midi_event snd_seq snd_pcm_oss snd_mixer_oss ieee1394 snd_pcm ehci_hcd snd_seq_device uhci_hcd snd_timer snd_page_alloc snd_util_mem sata_sil libata e7xxx_edac edac_mc snd_hwdep i2c_i801 e1000 serio_raw psmouse scsi_mod snd soundcore pcspkr i2c_core intel_agp agpgart ide_cd cdrom usbcore ext3 jbd CPU:0 EIP:0060:[]Not tainted VLI EFLAGS: 00010246 (2.6.20.1 #1) EIP is at module_put+0x20/0x52 eax: 6b6b6ceb ebx: 6b6b6b6b ecx: 0001 edx: e5bf esi: e9040b08 edi: 6b6b6b6b ebp: eae0bb3c esp: e5bf0f58 ds: 007b es: 007b ss: 0068 Process udevd (pid: 18662, ti=e5bf task=e6aaa030 task.ti=e5bf) Stack: eb3ff7bc c01839fe 0010 ed009b7c ed9291d0 c015124b f7ff2208 ed009b7c f7bd0678 ed009b7c c014ed88 0003 0003 f7bd0678 f7bd06f8 c014fd81 0003 0007 0003 e5bf c0102bce Call Trace: [] sysfs_release+0x2d/0x4c [] __fput+0x96/0x13c [] filp_close+0x51/0x58 [] sys_close+0x70/0xa7 [] sysenter_past_esp+0x5f/0x85 [] __sched_text_start+0x703/0x958 === Code: 00 89 f0 83 c4 0c 5b 5e 5f 5d c3 53 89 c3 85 c0 74 49 b8 01 00 00 00 e8 63 49 fe ff e8 e3 5a 07 00 c1 e0 07 8d 84 18 80 01 00 00 08 83 3b 02 75 0b 8b 83 88 05 00 00 e8 ad 45 fe ff b8 01 00 EIP: [] module_put+0x20/0x52 SS:ESP 0068:e5bf0f58 <6>note: udevd[18662] exited with preempt_count 1 BUG: scheduling while atomic: udevd/0x1001/18662 [] __sched_text_start+0x56/0x958 [] irq_exit+0x37/0x42 [] smp_apic_timer_interrupt+0x70/0x79 [] apic_timer_interrupt+0x28/0x30 [] __cond_resched+0x12/0x2c [] cond_resched+0x26/0x31 [] unmap_vmas+0x3d3/0x4df [] exit_mmap+0x7e/0x10a [] mmput+0x1d/0x78 [] do_exit+0x1b2/0x6d8 [] sys_vm86+0x9d/0x21d [] die+0x1f2/0x217 [] do_page_fault+0x442/0x510 [] do_page_fault+0x0/0x510 [] error_code+0x7c/0x84 [] module_put+0x20/0x52 [] sysfs_release+0x2d/0x4c [] __fput+0x96/0x13c [] filp_close+0x51/0x58 [] sys_close+0x70/0xa7 [] sysenter_past_esp+0x5f/0x85 [] __sched_text_start+0x703/0x958 === ___ All New Yahoo!
