This can affect other aacraid controllers such as PERC2/QC aka Adaptec
AAC-364 aka HP NetRAID 4M.
There are other causes that make it impossible to boot unless a 2.6.25
patch is included:
See launchpad bug #214814 "BUG: soft lockup - CPU#0 stuck for 61s!"
This appeared to be an aacraid issue, then firmware, then ACPI then PCI
and finally back to ACPI again!
