Unfortunately, hibernation has broken. This happened somewhere between Feisty's 2.6.20 kernel and the one I'm using now. (Although it could have been an update released in Feisty which broke things). I can hibernate, but after a short while being booted back up (and perhaps accessing some ACPI related thing, e.g. cpu scaling, unplugging AC etc.. it will crash (and due to being in X11 at the time, I've got no useful debug output to go on). Does anyone know specifically if something changed to fix suspend, (with SATA drives no less!), or anything which may have broken hibernate. (Which was broken before I updated from bios F.06 to the latest today) 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?
