I own the Acer Ferrari 4000 notebook and ever since I got it, it has been freezing up on me. It would freeze at different intervals. Sometimes no more than 47 mins, 1 hr 45 mins, 8 hrs or 1 day 17 mins. I using kernel-2.6.11.4-21.9-default. The errors that dmesg spits out are:

ACPI-0208: *** Warning: Error evaluating _BST ACPI-0352: *** Error: Looking up [Z00I] in namespace, AE_NOT_FOUND search_node ffff81003f845e40 start_node ffff81003f845e40 return_node 0000000000000000 ACPI-0446: *** Warning: [AE_NOT_CONFIGURED]: Could not resolve operands, AE_NOT_FOUND ACPI-1140: *** Error: Method execution failed [\_SB_.BAT1._BST] (Node ffff81003f845cc0), AE_NOT_FOUND

-------------------- powernow-k8: failing targ, change pending bit set

I tried booting up w/ acpi=off and that did not work. It would hang and the last thing on the screen would say System BIOS May be broken or something like that. I tried acpi=noacpi and that booted cleanly and it still froze at random intervals.

Froze also means locks up. I cannot use the keyboard, mouse...nothing...I can kill the power by turning the power button on and off. I am running the latest BIOS Update.

Any help would be grateful.

I *think* someone from AMD posted a week or two ago & said this was a hardware problem, they had duplicated it & escalated it, bla bla bla. Might check the archives to be sure. HTH & all that ....

The powernow-k8 message about the change pending bit is a known bug. We're still investigating. Random lockups are a new thing. My immediate suspicion is that its related to the ATI x700 chipset, which has problems on Linux prior to 2.6.13 or so. Updating to the latest mainline kernel may or may not help. -Mark Langsdorf AMD, Inc.
