Stephen,

Current linux-3.1-rc4+ is a total disaster on my BL460c G6

Few seconds after boot, I get "cmd_alloc returned NULL" messages
or "hpsa 0000:0c:00.0: resetting device 0:0:0:0"

Usually lot of files are corrupted, fsck needed, and full distro
reinstall as well.

I tested on two different machines, same result.
