I´m running an AMD64 with kernel 2.6.16.21-0.13 default. With dmesg I get the following warning: Aug 27 08:10:18 egal kernel: ACPI Warning (acpi_utils-0065): Invalid package argument [20060127] Aug 27 08:10:18 egal kernel: ACPI Exception (acpi_processor-0274): AE_BAD_PARAMETER, Invalid _PSS data [20060127] Aug 27 08:10:18 egal kernel: cpu_init done, current fid 0xe, vid 0x0 Aug 27 08:10:18 egal kernel: powernow-k8: ph2 null fid transition 0xe Aug 27 08:10:20 egal kernel: hdb: task_no_data_intr: status=0x51 { DriveReady SeekComplete Error } Aug 27 08:10:20 egal kernel: hdb: task_no_data_intr: error=0x04 { DriveStatusError } Aug 27 08:10:20 egal kernel: ide: failed opcode was: 0xef Aug 27 08:10:24 egal kernel: powernow-k8: internal error - pending bit very stuck - no further pstate changes possible Aug 27 08:10:24 egal kernel: powernow-k8: transition frequency failed. I postet this before an was told this is because of the Invalid_Pss data. Now I found this bug on bugzilla.kernel.org number 6782 for kernel 2.6.17-mm5 as resolved.PATCH_ALREADY_AVAILABLE http://bugzilla.kernel.org/show_bug.cgi?id=6782. Is this patch available for Suse 10.1 or will it be fixed in a new Kernel-Version? Thank you Michael
