They may not be responsible, but in my uninformed opinion these are the changes to look at more closely. Since plain bisection did not work well for you, maybe you should ask the maintainers involved in the ACPI patches for a priority list of patches to unapply for long-term tests. Also look at the diffstat whether there were changes to drivers which you use. Furthermore, maybe the few scheduler changes may play a role. But I don't understand what they do, so I may be completely off. http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.27.5 http://www.kernel.org/diff/diffview.cgi?file=%2Fpub%2Flinux%2Fkernel%2Fv2.6%2Fincr%2Fpatch-2.6.27.4-5.bz2 -- Stefan Richter -=====-==--- =-== ==-=- http://arcgraph.de/sr/ -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
