FC6 on Dell XPS710 H2C - OS "loses" hard drives
I inherited a crummy Dell XPS 710 - it's huge, heavy, loud, there's hardly any slots left, and a general PITA.
I installed FC6 x86_64. It uses the sata_nv driver to access the nVidia Mediashield (nforce 590, I think?) RAID -- 2 SATA drives in RAID1. Everything installed ok.
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.
