Trying to get ACPI suspend to work on my T61, I was eliminating modules from the configuration, so here's what I did: 1. I dropped down to singleuser mode: shutdown -p now 2. Started unregistering modules like so: # Typo # kldunload nvidia snv_hda sound nvidia0: detached kldunload: can't find file snv_hda # Fixed typo; forgot to remove nvidia from the invocation line. # kldunload nvidia snd_hda sound kldunload: can't find file nvidia # kldunload snd_hda sound pcm0: detached Fatal trap 12: page fault while in kernel mode cpuid = 0; apic id = 00 fault virtual address = 0xc6640fc0 fault code = supervisor read, page not present instruction pointer = 0x20:0xc0c46320 stack pointer = 0x20:0xe8661a6c frame pointer = 0x20:0xe8661a94 code segment = base rx0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 2955 (kldunload) [thread pid 2955 tid 100118 ] Stopped at hdac_audio_ctl_ossmixer_setressrc+0x5e: movl 0xf4(%eax),%ebx db> bt Tracing pid 2955 tid 100118 td 0xc6aed940 hdac_audio_ctl_ossmixer_setrecsrc(c6651000,0,0,e8661aa4,19,...) at hdac_audio_ctl_ossmixer_setrecsrc+0x5e mixer_setrecsrc(c6611160,0,c0c8f022,31d,0,...) at mixer_setrecsrc+0xae mixer_uninit(c6633680,c6633700,c0a86e28,c6633700,e8661b38,...) at pcm_unregister+0x315 pcm_unregister(c6633680,c6633700,c0a86e28,c6633700,e8661b38,...) at pcm_unregister+0x315 device_detach(c6633680,c0a86e28,1,0,e8661b88,...) at device_detach+0x68 device_delete_child(c5ee3b80,c6633680,e8661b88,0,0,...) at device_delete_child+0x2e hdac_detach(c5ee3b80,c5e1a060,c0a7b738,0,c5cf34c0,...) at hdac_detach+0x4e device_detach(c5ee3b80,0,0,c0c4d72c,c5d100000,...) at device_detach+0x68 driver_module_handler(c5cf34c0,1,c0c4d72c,e8661c10,c05f4159,...) at driver_module_handler+0x205 module_unload(c5cf34c0,c060c24a,c5d25100,83,0,...) at module_unload+0x64 linker_file_unload(c5cf6100,0,c67238e0,c6d0ad48,0,...) at linker_file_unload+0x1c5 kern_kldunloadf(c6aed940,2,0,e8661d38c0831737,...) at kern_kldunload+0xf8 kldunloadf(c6aed940,e8661cf8,e8661d38,c,e8661d2c,...) at kldunloadf+0x2d syscall(e8661d38) at syscall+0x2c4 Xint0x80_syscall() at Xint0x80_syscall+0x20 --- syscall (444, FreeBSD ELF32, kldunloadf), eip = 0x280d2453, esp = 0xbfbfe5fc, ebp = 0xbfbfee48 3.

running sh -c 'i=1; while [ 1 ] ; do echo "Try $i"; kldload snd_hda; kldunload snd_hda sound; : $(( i += 1 )); done' complains about sound.ko not being loaded, since unloading snd_hda.ko also unloads sound.ko. is this what you got too? i'm not sure this logic is correct. loading snd_hda.ko also loads sound.ko, since it depends on it. however i don't see why unloading snd_hda.ko also unloads sound.ko, since sound.ko has no dependencies and can exist without any snd_*.ko module. i wasn't able to trigger the panic however (command cancelled with i=350 or so). i'm running 9-CURRENT (r207154). -- Alexander Best

Hi Alexander, 1. How many cores and processors does your machine have? 2. Do you have SMP enabled? Thanks, -Garrett
Sorry... forgot to answer the questions.

Yes, because it's kldunload(2) unloads all dependent modules for snd_hda.ko not in use (in this case sound.ko). >> i'm not sure this logic is correct. loading snd_hda.ko also loads sound.ko, >> since it depends on it. however i don't see why unloading snd_hda.ko also >> unloads sound.ko, since sound.ko has no dependencies and can exist without any >> snd_*.ko module. The point was that there's a race condition if the time between both snd_hda.ko and sound.ko was done, s.t. not all of the pieces were cleaned up and/or communicated in the kernel. >> i wasn't able to trigger the panic however (command cancelled with i=350 or >> so). >> >> i'm running 9-CURRENT (r207154). Ok. This might have been fixed in a later revision that hasn't been MFCed from HEAD, but I really don't want to have to take down my server to test this... Thanks, -Garrett

Ok... now this is definitely non-standard. 1. My laptop is a dual-core Core2Duo proc (the full details are in the original PR). 2. I'm using SCHED_ULE, like most other folks post-7.x. I suggest using SCHED_ULE instead of SCHED_4BSD. You might only be able to run into the issue with SCHED_ULE because of how it schedules tasks. Thanks, -Garrett
