I have nearly the same behaviour here with a Dell D800 with the following sound card:
00:1f.5 Multimedia audio controller: Intel Corp.: Unknown device 24c5 (rev 01)
Subsystem: Dell Computer Corporation: Unknown device 014e
Flags: bus master, medium devsel, latency 0, IRQ 11
I/O ports at b800 [size=256]
I/O ports at bc40 [size=64]
Memory at f4fff800 (32-bit, non-prefetchable) [size=512]
Memory at f4fff400 (32-bit, non-prefetchable) [size=256]
Capabilities: [50] Power Management version 2
If I unload usb, network and sound modules before entering S3 I can
resume successfully.
Reloading the sound modules after resume the behaviour differs depending
on the order I load the modules in.
If I modprobe the snd modules _after_ usb or network modules the system
freezes.
If I modprobe the snd modules _before_ the others I get the following
messages in the syslog:
Mar 13 18:54:25 beja kernel: PCI: Setting latency timer of device
0000:00:1f.5 to 64
Mar 13 18:54:25 beja kernel: ALSA
/usr/src/modules/alsa-driver/kbuild/../pci/intel8x0.c:1969: AC'97 warm
reset still in progress? [0xffffffff]
Mar 13 18:54:25 beja kernel: Intel ICH: probe of 0000:00:1f.5 failed
with error -5
Is this problem hardware specific or does the alsa system not support
ACPI powermanagement?
I would really like helping to get this to work as this is the only
problem preventing me from using S3.
I could supply more information if necessary.
Thanks for any hints,
Christoph
