Every time I put my Dell Latitude D630 back in the docking station, the kworker kernel thread jumps to 100% CPU (i.e. one of the two cores) and stays there until reboot. /var/log/messages fills up with these errors: Jan 24 12:09:37 southern kernel: [254699.227808] ACPI Error: Method parse/execution failed [\SMI_] (Node ffff88007b772a88), AE_AML_INFINITE_LOOP (20110623/psparse-536) Jan 24 12:09:37 southern kernel: [254699.227821] ACPI Error: Method parse/execution failed [\DCKE] (Node ffff88007b778a60), AE_AML_INFINITE_LOOP (20110623/psparse-536) Jan 24 12:09:37 southern kernel: [254699.227828] ACPI Error: Method parse/execution failed [\NEVT] (Node ffff88007b772da8), AE_AML_INFINITE_LOOP (20110623/psparse-536) Jan 24 12:09:37 southern kernel: [254699.227835] ACPI Error: Method parse/execution failed [\_GPE._L1C] (Node ffff88007b778920), AE_AML_INFINITE_LOOP (20110623/psparse-536) Jan 24 12:09:37 southern kernel: [254699.227846] ACPI Exception: AE_AML_INFINITE_LOOP, while evaluating GPE method [_L1C] (20110623/evgpe-560) This is similar to bug 689848 and bug 714455, but it must be different because it is only triggered by a redock, and also I am running the 3.1.0-1.2-desktop kernel, which is quite a lot newer. Happy to provide further debug if required - problem is 100% reproducible. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
