I've gotten 2.6.11-rc4 to freeze after a swsusp, so I'm testing acpi=off now.
As Murphy's Law would have it, I usually get these lockups at inopportune times when I really don't want to have to punch the power button, like when I'm in a hurry trying to find something or during long-running network backups. It also does it when sitting idle, so this isn't a rule.
I've run most of a backup from an NFS mount to the local drive (for about 10 minutes), stopped it, swsusp, ran another backup, and it's looking fine so far.
To be sure that it's not going to freeze, I'd almost have to let it go for a week, though, because sometimes I had just gotten lucky and not seen the issue for upto 4 days at a time.
Assuming disabling ACPI causes my trouble to go away, what's my next step in debugging this issue? I'd hate to just leave it at "Don't use ACPI."
