Wysocki 2011-01-04 22:43:43 --- OK, thanks for testing! Apparently, with the patch from comment #44 _OSC is not executed on your system, so it doesn't use native PCI Express services and that's why the GPE storm doesn't appear any more (so the patch definitely helps).

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".

https://bugzilla.kernel.org/show_bug.cgi?id=20232 --- Comment #36 from Ozan Caglayan 2010-12-29 15:02:14 --- Yes exactly. But, What I've tried as 2.6.37_rc7-git4 + patch in comment#23 was not vanilla at all. It's carrying a patch from upstream that seems related to the issue so maybe it was this commit which fixed the issue: commit 885c252ffb059dc493200bdb981bdd21cabe4442 Author: Matthew Garrett Date: Thu Dec 9 18:31:59 2010 -0500 PCI: _OSC "supported" field should contain supported features, not enabled ones From testing with Windows, the call to the PCI root _OSC method includes the full set of features supported by the operating system even if the hardware has already indicated that it doesn't support ASPM or MSI. https://bugzilla.redhat.com/show_bug.cgi?id=638912 is a case where making the _OSC call will incorrectly configure the chipset unless the supported field has bits 1, 2 and 4 set. Rework the functionality to ensure that we match this behaviour. Anyway, I'll try with a vanilla 2.6.37_rc8 with and without the patch in comment29 to see the outcome. -- 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

https://bugzilla.kernel.org/show_bug.cgi?id=20232 --- Comment #21 from Florian Mickler 2010-12-01 17:53:05 --- The load average is unrelated to this bug. Check the patch in bug #16525 for that.

But even on a basic console login which stays idle for hours the load average stays always above 1. The output of top doesn't show any surprising, no task which uses the cpu excessively.

We didn't have much time to bisect the issue but if we can't find out the cause without bisecting, I'll try to bisect too. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are watching the assignee of the bug. -- Beautiful is writing same markup.
