Sometimes my Thinkpad T60 pauzes for a couple of seconds. This means the all programs are frozen and when playing audio file it loops. This can also be triggered by pulling out the power plug or plugging it back in.

As from the email Steve wrote:

This does not occur for 3.14, so there is some sort of regression that needs to be corrected.

One sequence that appeared several times was

I didn't figure out which event this was for.

If I repeat pulling the power plugin and reinserting it after some time my system will freeze completely. Its frozen in the sense that there is no more activity in PM, mouse and keyboard are not responding. Steve did find out the debug kernel was still alive. Not even a memory dump could be made with CTRL ALT F10.

The file short_machine_freeze.txt is output of the PSD (buffer machine empty on purpose). This "Emm" entries at the end could point to what is happening. This dump from acpica$ was made directly after such a short lockup was heard in the audio.

But even when playing no audio Steve and I have also observed this type of freeze and when we went inside with the kernel debugger to find it in this loop. It can be UNIAUD, that is true, we need todo more debugging later today. However this malfunctions did not occur with ACPI 3.14 or earlier.

When I had these short freezes without AUDIO playing I could not type for a few seconds.

Later today I attach the output of the kernel debugger that is easier to read then the stuff copy pasted in the ticket.

The file genereal_dump.txt is dump of the T60 starting up with ACPI 3.15.

These freezes occur both with the switch /APIC /SMP and the PSD loaded without any switches.
