Thanks for that. I invoke it from /etc/rc.local, and then get:

$ sudo setpci -s 18.0 0x68.l
0f20cc0f
$ sudo rdmsr 0xc001001f
100000008

Previously that was:

$ sudo setpci -s 18.0 0x68.l
0f00cc0f
$ sudo rdmsr 0xc001001f
8

However, putting in that one audio CD still crashes the machine:

Original (identical, from a quick glance) MCE is at

Grüße,
