Description Juan Manuel Borges Ca 2007-11-12 12:37:59 UTC

Most recent kernel where this bug did not occur:
Distribution: Fedora 8
Hardware Environment: PC, Asus motherboard
Software Environment:
Problem Description:
 Hello.

 This message appears at boot:
ACPI: Invalid PBLK length[5]

 Maybe related, the system doesn't want to hibernate, but I didn't tested it in  
months, since I don't needed this feature in my PC, for now.

 Tell me what information you may find useful.



Steps to reproduce:
Boot the computer.

Juan, we need more detailed report. e.g. Asus mobo model name, lspci output, etc.

Hi, Juan
      According the ACPI spec, the Processor block should be defined as the following:
     (Processorname, ProcessorID, PBLKaddress PBLKLen)
     PBLKLen is the length of processor register block in byts and either 0(for no PBLKaddress) or 6. 
But the processor block in your BIOS is defined as :
     Processor (\_PR.CPU0, 0x00, 0x0000E410, 0x05)
     The pblock length is different with the length required by ACPI spec.
So the OS reports that ACPI: Invalid PBLK length[5].

It is appropriate to fix this problem by BIOS update.
Thanks.

PBLK is needed for the processor C-state and T-state control.
As it's a desktop, maybe this is not needed/support by your processor,
could you attach the content of /proc/cpuinfo please?
