Today I noticed an oops when resuming from sleep. Here's what I get on the screen console: ---8<--- adb: starting probe task... adb devices: [2]: 2 c4 [3]: 3 1 [7] 1f ADB keyboard at 2, handler 1 ADB mouse at 3, handler set to 4 (trackpad) adb: finished probe task... tumbler: i2c is not initialized Oops: kernel access of bad area, sig: 11 [#1] NIP: DA378C3C LR: DA468E0C SP: D4F13D70 REGS: d4f13cc0 TRAP: 0301 Not tainted MSR: 0000b032 EE: 1 PR: 0 FP: 1 ME: 1 IR/DR: 11 DAR: 00000006, DSISR: 40000000 TASK = d74920c0[1233] 'pmud' Last syscall: 54 GPR00: DA468E0C D4F13D70 D74920C0 00000000 00000040 00000000 00000000 00000040 GPR08: 00000002 FFFFFFFF D74920C0 00000000 2DE985CF Call trace: [da468e0c] snapper_set_capture_source+0x28/0x38 [snd_powermac] [da46936c] tumbler_resume+0xa0/0x138 [snd_powermac] [da466318] snd_pmac_resume+0xf4/0xf8 [snd_powermac] [da466364] snd_pmac_sleep_notify+0x48/0x54 [snd_powermac] [c030788c] 0xc030788c [c0307fe0] 0xc0307fe0 [c03084c4] 0xc03084c4 [c0308d2c] 0xc0308d2c [c0067c04] sys_ioctl+0xdc/0x2f4 [c0007600] ret_from_syscall+0x0/0x44 eth0: Link is up at 100 Mbps, full-duplex. eth0: Pause is disabled --->8--- And the system is completely hung (I've copied it by hand, so I could have made a mistake typing). I've noticed that if I put the iBook to sleep having unloaded alsa, it resumes ok. Having alsa loaded, I can reproduce it 100% of the times.
