Well, we use the ubuntu tree: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-hardy.git;a=summary They have a few more patches applied: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-hardy.git;a=history;f=include/asm-x86/msr.h;h=cfe169475b5b50a448326ef3c34f50100ac83faf;hb=HEAD Seems the last two patches cause the problem. I just wonder if we need those bariers or not? http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-hardy.git;a=commitdiff;h=198b348d96c9769153e72ca2461f8d841ddff1cc - Dietmar > -----Original Message----- > From: Jan Kiszka [mailto:jan.kiszka@xxxxxxxxxxx] > Sent: Mittwoch, 28.
