You may try the kernel.org kernel 2.6.22-rc2 with the hibernation and suspend patchset available from http://www.sisk.pl/kernel/hibernation_and_suspend/2.6.22-rc2/patches . > After resume from suspend, I see: > > dmesg | grep ACPI | grep Error > [ 4763.428000] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.C241] (Node df94c9dc), AE_AML_PACKAGE_LIMIT > [ 4763.428000] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.C002.C0DC.C349._STM] (Node df94fba8), AE_AML_PACKAGE_LIMIT > [ 6417.528000] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.C241] (Node df94c9dc), AE_AML_PACKAGE_LIMIT > [ 6417.528000] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.C002.C0DC.C349._STM] (Node df94fba8), AE_AML_PACKAGE_LIMIT > > Is this anything to worry about - should I post a dsdt for the new bios? This means we are unable to set the IDE controller transfer timings after the resume. I don't know how serious this is in practice, though. Greetings, Rafael
