To my knowledge bad VPD data had only been found on early prototypes, as they
avoided the typical manufacturing process. Regardless, we do try to be
preventative about this type of thing, just in case.

If I set /proc/sys/vm/dirty_ratio to 5 the write lockup happens within
the first MilliSecond, at about 100MB per file system.
If I slew the dirty_ratio to 80, the lockup happens
at about 2GB per file system.
2.6.21-rc4 has the same symptoms, and same lockups.
It appears that mptsas is dropping
My local kernel guru recognized this problem as a duplicate of the
LSI8408E bus lockup problem. The controller gets flooded with work,
and just climbs under a rock to hide. In the 8408E case, it
froze the PCI-e bus :-)
