reproducible SCSI problems with Adaptec and EasyRAID II

[Christian Hammers <ch@westend.com>]

Hello

I experience kernel panics whenever I turn on my computer[1] and the
RAID[2] on after they both where off. When resetting or power cycling the
computer alone it works fine afterwards.

This error occurs with two different external cables. 

We had have similar errors a while before (also posted here) that occured 
whenever a scsi tape was in use and never got a working fix. As we're using 
the RAID systems on two other computers and never got it before buying the 
dual cpu (but sadly not exactly but a couple of days after we installed the 
new board) I suspect this to be the cause.

Any help appreciated!

thanks,
