[Bug 577702] Re: ACPI errors at boot (HP 8540w Elite Workstation)

[FiX]

Tested against main-line kernels:

2.6.33-02063303
2.6.34-020634rc6

In both cases, the ACPI error message at boot is no longer here. But:

1) The pcie error messages remain:

[  179.311138] pcieport 0000:00:03.0: AER: Corrected error received: id=0018
[  179.311147] pcieport 0000:00:03.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=0018(Receiver ID)
[  179.311150] pcieport 0000:00:03.0:   device [8086:d138] error status/mask=00000040/00002000
[  179.311227] pcieport 0000:00:03.0:    [ 6] Bad TLP               

2) The system can still not suspend (USB 3.0):

[  247.409976] PM: Syncing filesystems ... done.
[  247.609594] PM: Preparing system for mem sleep
[  247.609602] Freezing user space processes ... (elapsed 0.01 seconds) done.

[  247.768899] PM: Device usb3 failed to suspend: error -2
[  247.768901] PM: Some devices failed to suspend

[  247.809404] PM: resume devices took 0.040 seconds
[  247.809716] PM: Finishing wakeup.

3) kacpid still at 100% CPU

Will test without the nvidia module.
