Sound driver problem ? 
 
 
Severity is major since I can hardly work with the system.
Comment 1 Klaus Kämpf 2005-08-09 09:25:43 UTC
Reverting to preview4 kernel (kernel-default-2.6.13_rc4_git4-3) brings my 
system back to a saner state 
Comment 2 Takashi Iwai 2005-08-09 09:35:26 UTC
I suspect it's rather a problem with ACPI debug option.
(kacpid has nothing to do with sound :)
Comment 3 Klaus Kämpf 2005-08-09 09:37:57 UTC
Andreas also suggested the debug option. However, with the beta1 kernel I 
didn't see debug output. But with the preview4 kernel, /var/log/messages now 
shows lots of:

Aug  9 11:36:53 heron kernel: [ACPI Debug]  String: [0x0F] "Entering TIN2()"

Comment 4 Thomas Renninger 2005-08-09 16:22:55 UTC
Use ec_burst=burst boot param, that should help.
