I have a Fujitsu E7110 laptop with a builtin audio card. This is what lspci
reports...
00:1f.5 Multimedia audio controller: Intel Corp. 82801CA/CAM AC'97 Audio (rev
02)
Subsystem: Citicorp TTI: Unknown device 1177
Flags: bus master, medium devsel, latency 0, IRQ 11
I/O ports at 1000 [size=256]
I/O ports at 1880 [size=64]
I am running 2.6.4-rc2 kernel, and I have been trying to get ACPI S3 (suspend
to ram) to wake up correctly. One of the problems that I am encountering is
that with the sound modules loaded (I have always had success with
snd_intel8x0 on the same hardware) coming back from sleep freezes my laptop
hard. If I rmmod *all* the sound-related modules before going to sleep, the
laptop resumes without a hitch. However, if I attempt to modprobe
snd_intel8x0 after resume, I get a hard freeze again. I cannot recover any
debug output, because the end of /var/log/messages is garbled on reboot.
I have looked on ALSA and ACPI mailing lists and have not been able to find a
satisfactory answer to this. It appears some people can reinsert the intel
driver after resume, and they get their audio back. I have no such luck.
Could you please provide some tips on how I can help address this problem?
For instance, what other information about my setup should I post. Is there
some documentation on audio power management under ACPI that I am overlooking?
Thank you very much,
Ilya
