Compiling with 2ea5521022ac8f4f528dcbae02668e02a3501a5a as HEAD fixed s2disk. I apologize for not having understood what was meant the first time around. (2) Bisecting between that and 2.6.30 narrowed down the "problem" commit to: 2f0d0fd2a605666d38e290c5c0d2907484352dc4. This is not really a problem (see below). (3) Between 2.6.26 and 2.6.28 things broke for me (CPU ran about 17 degrees hotter while idle). The fix was noapic, nolapic, and pci=noacpi. This issue was resolved between 2.6.28 and 2.6.30.2 but pci=noacpi was needed to prevent IRQ problems (because IOAPIC support had been removed from my kernel). It turns out pci=noacpi, 2f0d0fd2a605666d38e290c5c0d2907484352dc4, and s2disk don't get along. (4) I am happy to confirm that 2.6.30.4 works great with the re-insertion of IOAPIC uniprocessor support in the kernel and removing all APIC and ACPI boot parameters. Sorry for the false alarm. ~Andy -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug.
