This is with the latest maintenance update kernel? Then this is a duplicate -> marking as such. Please reopen if it is not. There should already be or there should be soon another update kernel fixing this (should all be stated in the other bug..). *** This bug has been marked as a duplicate of bug 357598 *** I would not call this a duplicate of bug 357598 for these reasons: * bug 357598 mentions the Intel speedstep kernel modules, but does not mention the AMD powernow-k8 kernel modules. * bug 357598 is about missing kernel modules, because of a kernel build config error; in my bug, the kernel module exists, but causes an exception on trying to load it with modprobe. * bug 357598 is for Product openSUSE 10.3, while this bug is for product SUSE Linux 10.1. They use different kernels; 2.6.22 for 10.3 and 2.6.16 for 10.1. To answer your question, yes this is the latest maintenance update of the SUSE kernel updated from SUSE's online repository: 2.6.16.54-0.2.5. I've reverted to the prior maintenance release, 2.6.16.54-0.2.3, and there are no problems with -0.2.3, everything else in the system remaining the same. *** This bug has been marked as a duplicate of bug 358354 *** 10.1 is SLES based, please try this kernel: ftp.suse.com/pub/projects/kernel/kotd/SLES10_SP1_BRANCH/x86_64/kernel-default.rpm You can check the changelog rpm -qp --changelog kernel-xy.rpm |less This is the fix: * Mon Feb 11 2008 - trenn@suse.de - patches.arch/x86_64_powernow_display_cpus_correctly.patch: Output cleanup for CPUs in powernow-k8 driver (#334743). Check for possible divide through zero. The change will be in the next update kernel. |
There's a problem with the powernow-k8 module with kernel-default-2.6.16.54-0.2.5 (x86-64). It worked fine under -0.2.3. Note the last line in this /var/log/messages extract.
