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

SCSI Driver

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