SubjectRAID, 2.4.2 and Buslogic

Leonard,

My story is somewhat similar to what Dick Johnson has encountered except
this is with 2.4.2 running on a pentium 200.

I encountered an oops last night while untarring a file. Upon reboot, it
appears that the partition labels disappeared along with the superblock.
Unfortunately, I was not able to recover and had to redo the setup from
scratch.


Here is the lspci output

Unfortunately, the System.map was deleted during a compile but attached is
the dmesg output.

PS. Is there a minimum processor speed requirement to do RAID? I know the
pentium 200 is pretty wimpy but if this is the failure mode it was
certainly unexpected.
