--- Comment #39 from Ozan Caglayan <o...@pardus.org.tr> 2010-12-31 07:55:39 --- Okay, I'll try to resume what's going on as I think I've caused a little bit of confusion: - 2.6.36.x is still showing the issue on those laptops - The problem goes away on 2.6.36.x with pci_ports=compat but this gives a backtrace while unregistering a driver (patch to fix is available in comment #23) - A complete solution is offered within the patch in comment #29 Then I tried 2.6.37_rc7-git4 with the patch in comment #23 to see at least if the backtrace is fixed when booting with pcie_ports=compat. A plain reboot (with no pcie_ports=compat) cured the kworker issue. Either the switch to 2.6.37_rc* cured the issue or the patch that I've taken from fedora f-15 entitled "PCI: _OSC "supported" field should contain supported features, not enabled ones". That was the patch I misleadingly told as "from upstream", sorry. Then last night, I switched to 2.6.37_rc8 which already contains your patch in comment #23. I also put the patch in comment #29 on top of it and dropped the "PCI: _OSC .." patch from Matthew Garrett. But unfortunately a lot of machines broke while booting this kernel. I'll send the photo just after this comment. --- Comment #40 from Ozan Caglayan <o...@pardus.org.tr> 2010-12-31 08:01:57 --- Created an attachment (id=41992) --> (https://bugzilla.kernel.org/attachment.cgi?id=41992) 2.6.37_rc8+patch#29 ACPI trace --- Comment #41 from Rafael J. Wysocki <r...@sisk.pl> 2011-01-02 00:26:34 --- The crash seems to be caused by the patch from comment #29, which apparently tries to parse the HEST table too early. However, you appear to say that the patch from comment #29 on top of 2.6.36.y works correctly. Is that also the case on machines that crash with 2.6.37-rc8 + the patch from comment #29 (I mean, if those machines are booted with 2.6.36.y + patch from comment #29, do they boot correctly or crash)? -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ------------------------------------------------------------------------------ Learn how Oracle Real Application Clusters (RAC) One Node allows customers to consolidate database storage, standardize their database environment, and, should the need arise, upgrade to a full multi-node Oracle RAC database without downtime or disruption http://p.sf.net/sfu/oracle-sfdevnl _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
