<DIV><FONT face=Arial size=2>Also shows up single processor (different machine,
same chipset 53C875).&nbsp; Looks like a possible SCSI Scipts error.&nbsp;
FENRIS, unlike UNIX FS's will talk to more than one disk or partition
concurrently since a volume can have multiple segments strip[ed across several
drives.&nbsp; May be exposing some timing condition with the way I am calling
breada abd bread.</FONT></DIV>

<DIV><FONT face=Arial size=2>More on this -- am also getting "..could not get
a free page...".&nbsp; Tracing with a logic analyzer shows memory
corruption.&nbsp; Looks like an errant Data Transfer.&nbsp; Machine is a dual
processor 500Mhz PIII Server.&nbsp; Problem only shows up when SMP is
active.&nbsp; Will attempt to reproduce using single processor.</FONT></DIV>

<DIV><FONT face=Arial size=2>It's busted in all three.&nbsp; Not my bug, I
will get Oops specific info.&nbsp; Complains that the LRU Block list has
been corrupted.&nbsp; Only happens with the NCR driver and the 53c875
Chipset.&nbsp; Could be a scripts bug since the NCR SCSI chip can program
it's own DMA from the SCSI scripts.</FONT></DIV>
