Description Folkert van Heusden 2005-07-15 06:26:01 UTC

Distribution: not applicable (selfmade kernel)
Hardware Environment: HP Pavillion zv5231ea laptop
Software Environment:
Problem Description: when NOT giving 'pci=noacpi' on the kernel-commandline, the
kernel spits out some debugging about the audio-device in this laptop and from
then on refuses to produce any sound. WITH pci=noacpi, everything works fine.

(the timeouts appear a lot more by the way, I shortened things)

I've discussed this problem with Andrew Morton, perex@suse.cz and tiwai@suse.de
and Andrew asked me to submit this problem into bugzilla.

Comment 1 Andrew Morton 2005-07-29 00:28:37 UTC

Does this still happen in 2.6.13-rc4?

Are you able to identify an early 2.6 version which 
didn't need the `pci=noacpi'?

Comment 2 Len Brown 2005-08-14 22:43:34 UTC

Is "acpi=noirq" a sufficient workaround, or is "pci=noacpi" required?
Does "pnpacpi=off" make any difference?

Is this still an issue in the latest kernel.org kernel (eg. 2.6.13-rc6)?

Was there an earlier ACPI-enabled kernel where this worked,
or has it always been broken?

Comment 3 Folkert van Heusden 2005-08-23 12:20:15 UTC

acpi=noirq works fine too. So: both pci=noacpi and acpi=noirq work fine.
Should I try pnpacpi=off as well?

Comment 4 Len Brown 2007-08-18 20:48:31 UTC

Still a problem with 2.6.22.stable?

if yes, do please try "pnpacpi=off" all by itself.

Also, please attach the dmesg and /proc/interrupts for
when booting with and without "acpi=noirq".  Also,
please attach a single copy of the output from
acpidump and lspci -vv

Comment 5 Len Brown 2007-09-06 16:21:28 UTC

please re-open if still a problem in 2.6.22.stable or later.
