dmesg output 2.6.26
added me to CC Just installed kernel 2.6.18 and 2.6.24 on Debian Lenny and got same error like with 2.6.26 and 2.6.29. So problem is not kernel-dependent, it should be something with libraries. Sorry for trouble... Reopening because found that is is definitely kernel problem. The bug appears only if acpi_cpufreq module is loaded. Removing acpi_cpufreq using rmmod -f or preventing it from loading heals the problem. Also removing regression tag and adding kernel versions 2.6.18 and to 2.6.24 to broken list. Also found similar report http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=362708 which is 3 years old. It was reported to Debian bug tracking system and was closed in 2008 with strange comment "in newer kernels acpi_cpufreq is gone". Please contact me if you need any further info. PS Subject of the bug should be renamed into something like "acpi_cpufreq and snd_atiixp conflict", but do not know how to do this. Also I am not able to select 2 components (acpi cpufreq and alsa) at the same time. If acpi_cpufreq is not loaded at boot time, then the line [ 90.530276] atiixp: codec reset timeout does not appear in the dmesg output after reboot sounds interesting. please attach the acpidump output of your laptop.

acpi dump
this is really weird because the acpi-cpufreq should be a null as there is no ACPI P-state support on this laptop. please attach the output of "cat /proc/interrupts" and dmesg when acpi is on and snd_atiixp is not working. ping... Created attachment 25168 [details]
2.6.30 /proc/interrupts when sound broken
This is cat /proc/interrupts created when sound was broken. This was triggered by enabling in BIOS advanced option "processor power management"
Sorry for big delay, i was on vacations. Will try to answer ASAP now. There is an advanced option in BIOS "Processor Power Management". If this option is enabled, CPU frequency stepping is enabled, module acpi_cpufreq is loaded and all kinds of problems appear (in addition to broken sound, PC sometimes locks up when CPU get high frequency). If this BIOS option is disabled, CPU frequency is fixed to 1600MHz, module acpi_cpufreq is not loaded and no problem appear. If this BIOS is enabled, but acpi_cpufreq is not loaded or removed, then sound works OK. (In reply to comment #8) > this is really weird because the acpi-cpufreq should be a null as there is no > ACPI P-state support on this laptop. > Hah, I see, please attach the acpidump when the "Processor Power Management" is enabled in BIOS. please also attach the output of " grep . /sys/devices/system/cpu/cpu*/cpufreq/*" when the sound is not working.

2.6.30 cpu_dump cpu stepping on and broken sound
2.6.30 acpidump with bios option which enables cpu stepping on and broken sound

2.6.30 /sys/devices/system/cpu/cpu*/cpufreq cpufreq on broken_sound
2.6.30 cpufreq on broken_sound, output of
# grep . /sys/devices/system/cpu/cpu*/cpufreq/*
added 2.6.30 it seems that ACPI is doing nothing wrong here. The p-state exported by BIOS also seems normal (1.6G and 2.4G). (In reply to comment #5) > If acpi_cpufreq is not loaded at boot time, then the line > > [ 90.530276] atiixp: codec reset timeout > > does not appear in the dmesg output after reboot this may be a clue. re-assign to the alsa category to see if we can get any help there. If this problem is still seen with modern kernels please update/re-open the bug |
Created attachment 22030 [details] lspci output 2.6.26 Hardware: Toshiba Satellite a30 (lspci in attachment), with sound card ATI Technologies Inc IXP150 AC'97 Audio Controller. Last working kernel: 2.6.18 Not working: 2.6.26, 2.6.29 Sound stops working after upgrading from kernel 2.6.18 (Debian Etch ) to kernel 2.6.26 (Debian Lenny). Installing kernel 2.6.29 (from lenny-backports) does not help. Additionaly 2.6.29 locks up after some time. Often the very first time I start playing music after reboot, sound works for certain period of time. Second time xfmedia hangs, mplayer prints out: [AO_ALSA] alsa-lib: pcm_hw.c:405:(snd_pcm_hw_hwsync) SNDRV_PCM_IOCTL_HWSYNC failed: Broken pipe At this time nothing new appears in dmesg. During boot I got following suspicious messages (full dmesg is in attachment): MP-BIOS bug: 8254 timer not connected to IO-APIC ..trying to set up timer (IRQ0) through the 8259A ... failed. ...trying to set up timer as Virtual Wire IRQ... works. [snip] atiixp: codec reset timeout atiixp-modem: no codec available After lots of experimenting with kernel boot options, I found out that sound works with option "acpi=off". Other options, like noapic, acpi={noirq,strict,force}, pci=noacpi, nolapic_timer do not help. Using acpi=off is not a very nice solution, because it switches off other usefull features. Suspicious kernel messages mentioned above, appear also with option "acpi=off". $ cat /proc/interrupts CPU0 0: 127460 local-APIC-edge-fasteoi timer 1: 5015 IO-APIC-edge i8042 8: 2 IO-APIC-edge rtc0 12: 184 IO-APIC-edge i8042 14: 14311 IO-APIC-edge ide0 15: 0 IO-APIC-edge ide1 16: 4 IO-APIC-fasteoi ohci1394, yenta, radeon@pci:0000:01:05.0 17: 2 IO-APIC-fasteoi ATI IXP 19: 41239 IO-APIC-fasteoi ohci_hcd:usb1, ohci_hcd:usb2, ehci_hcd:usb3, eth0 21: 1568 IO-APIC-fasteoi acpi NMI: 0 Non-maskable interrupts LOC: 62299 Local timer interrupts RES: 0 Rescheduling interrupts CAL: 0 function call interrupts TLB: 0 TLB shootdowns TRM: 0 Thermal event interrupts SPU: 0 Spurious interrupts ERR: 0 MIS: 0
