Hi Mario,

>From kern.log you can see the #32, then the #33 kernel:

Sep 20 03:29:00 mythtv-desktop kernel: [23704.548916] Pid: 3916, comm:
lirc Tainted: P 2.6.35-22-generic #32-Ubuntu 945P-S3 /

Sep 20 23:21:58 mythtv-desktop kernel: [ 2102.050263] Pid: 1948, comm:
lirc Tainted: P 2.6.35-22-generic

So I assume the answer is yes?

Cheers

Douglas

#33-Ubuntu 945P-S3 /
