After running for a few hours the OS will lose the ability to write to the disks. The kernel errors with "journal commit I/O error" when it can't write the ext3 journal to the disk. After this any command will generally result in "end_request: I/O error, dev sda".
At this point I can't even shutdown cleanly and a hard restart is necessary.
I tried passing iiommu=soft at boot time but it didn't seem to make a difference.
Nobody has any ideas?? Do you need more information? If so, what? I'll be glad to oblige.
This is a REAL nuisance...
