Bisect stopped at commit 7f74f8f28a2bd9db9404f7d364e2097a0c42cc12 -------------------- [~/repository/kernel]$ git bisect good 7f74f8f28a2bd9db9404f7d364e2097a0c42cc12 is the first bad commit commit 7f74f8f28a2bd9db9404f7d364e2097a0c42cc12 Author: Andreas Herrmann Date: Thu Feb 24 15:53:46 2011 +0100 x86 quirk: Fix polarity for IRQ0 pin2 override on SB800 systems On some SB800 systems polarity for IOAPIC pin2 is wrongly specified as low active by BIOS. This caused system hangs after resume from S3 when HPET was used in one-shot mode on such systems because a timer interrupt was missed (HPET signal is high active).
