William, Please test if this is still necessary when you are running ACPICA 20061109. You can get that release in several ways: A plain patch on top of 2.6.19: http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/patches/test/2.6.19/acpi-test-20061109-2.6.19.diff.gz or pull it from git: git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux-acpi-2.6.git acpica In both cases, you'll result in a 2.6.19 base plus only the ACPICA update. thanks, -Len On Monday 04 December 2006 17:49, akpm@xxxxxxxx wrote: > From: William Morrow <william.morrow@xxxxxxx> > > On some BIOSen, the GPE bit will remain set even if it is disabled, > resulting in a interrupt storm.
