Hello,

Okay, sorry. I did not read the leading text inside kernel-parameters.txt. Just did a grep acpi and looked for the listed lines.

I will try this later, What does this timer-fix mean for my system?

I have stopped the sound and have removed all sound modules (Init-script did this for me ;-) ) I have checked, if the modules had been removed (lsmod). I did a cat /proc/interrupts and: IRQ22 had ohci_hcd for itself. After that I tried to do a hotplug restart, but the init-script was unable to restart it. It did nothing, just waiting. I could not break it with CTRL+C. So, USB does not work, even when sound is not running.
I also tested my SCSI-controller, but that seems to work okay, although it had some problems aborting a command (I copied a 400MB file and pressed CTRL+C after about 230MB). Here is the output:
Apr 25 19:49:34 [kernel] ISOFS: changing to secondary root Apr 25 19:52:43 [kernel] scsi1:0:4:0: Attempting to queue an ABORT message - Last output repeated 3 times - Apr 25 19:53:28 [kernel] Recovery code awake Apr 25 19:53:28 [kernel] scsi1 (4:0): rejecting I/O to offline device

I have booted the system without specifying apic (Seems to be noapic, because of XT-PIC in /proc/interrupts) and with lapic. In both cases, TV is working without any problems. Only specifying apic explicitly, freezes the system.
