Fantastic! Following the information above I did a search for amd76x_edac and found Debian bug #363682.
Blacklisting amd76x_edac solves my problem (two problems actually, since the messages in my syslog which I reported as bug #55204 stems from EDAC too). EDAC was introdused in 2.6.16, but for me it seems that it isn't quite there yet. Maybe EDAC should be blacklisted on this release? -- fglrx driver can't find AGP => disables DRI... https://launchpad.net/bugs/58193 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
