The system looks okay when idle, but heavy Disk I/O (onboard SCSI, basically tar cfz) produces the hang within a few minutes. (No hangs unless the amd76x_pm module is loaded.) The board is otherwise quite stable (i.e. no unexplained hangs/crashes/panics). Any suggestions on how to approach this? The C2 idle loop code is what changed for me (from 2.4.19pre10-ac2). But I don't know enough about ACPI to know where to start... what info would help? Oh, and this driver (while it works) shaves a full 140W off the power consumption. Cool.
