Public bug reported: Hi there, during hibernation I see some strange messages, but OK, hibernation is not officially supported.
The problem is, that I've got errors in system log (dmesg) even without any hibernation, just normal boot from powered-off computer. Here is what I've got: $ dmesg | grep -iE "fault|error|warn" | grep -v default [ 0.000000] ACPI BIOS Warning (bug): 32/64X FACS address mismatch in FADT: 0xAAFE4E40/0x00000000AAFE4D40, using 32-bit address (20141107/tbfadt-283) [ 7.943709] ACPI Warning: SystemIO range 0x0000000000000428-0x000000000000042f conflicts with OpRegion 0x0000000000000400-0x000000000000044f (\GPIS) (20141107/utaddress-258) [ 7.943714] ACPI Warning: SystemIO range 0x0000000000000428-0x000000000000042f conflicts with OpRegion 0x0000000000000400-0x000000000000047f (\PMIO) (20141107/utaddress-258) [ 7.943721] ACPI Warning: SystemIO range 0x0000000000000540-0x000000000000054f conflicts with OpRegion 0x0000000000000500-0x000000000000057f (\GPIO) (20141107/utaddress-258) [ 7.943724] ACPI Warning: SystemIO range 0x0000000000000540-0x000000000000054f conflicts with OpRegion 0x0000000000000500-0x0000000000000563 (\GP01) (20141107/utaddress-258) [ 7.943727] ACPI Warning: SystemIO range 0x0000000000000530-0x000000000000053f conflicts with OpRegion 0x0000000000000500-0x000000000000057f (\GPIO) (20141107/utaddress-258) [ 7.943730] ACPI Warning: SystemIO range 0x0000000000000530-0x000000000000053f conflicts with OpRegion 0x0000000000000500-0x0000000000000563 (\GP01) (20141107/utaddress-258) [ 7.943733] ACPI Warning: SystemIO range 0x0000000000000500-0x000000000000052f conflicts with OpRegion 0x0000000000000500-0x000000000000057f (\GPIO) (20141107/utaddress-258) [ 7.943735] ACPI Warning: SystemIO range 0x0000000000000500-0x000000000000052f conflicts with OpRegion 0x0000000000000500-0x0000000000000563 (\GP01) (20141107/utaddress-258) [ 8.768176] ACPI Error: Method parse/execution failed [\_SB_.PCI0.GFX0._DSM] (Node ffff88014a8b94b0), AE_AML_PACKAGE_LIMIT (20141107/psparse-536) [ 8.768189] ACPI Warning: \_SB_.PCI0.GFX0._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20141107/nsarguments-95) [ 8.768245] ACPI Warning: \_SB_.PCI0.GFX0._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20141107/nsarguments-95) [ 8.768329] ACPI Error: Method parse/execution failed [\_SB_.PCI0.GFX0._DSM] (Node ffff88014a8b94b0), AE_AML_PACKAGE_LIMIT (20141107/psparse-536) [ 8.768334] ACPI Error: Method parse/execution failed [\_SB_.PCI0.PEG0.GFX0._DSM] (Node ffff88014a8ce9b0), AE_AML_PACKAGE_LIMIT (20141107/psparse-536) [ 8.768342] ACPI Warning: \_SB_.PCI0.PEG0.GFX0._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20141107/nsarguments-95) [ 8.768394] ACPI Warning: \_SB_.PCI0.PEG0.GFX0._DSM: Argument #4 type mismatch - Found [Buffer], ACPI requires [Package] (20141107/nsarguments-95) [ 12.286131] EXT4-fs (sda3): re-mounted.
