NetBSD 1.5.3_RC2 and 1.6_BETA4 generate different kernel messages at boot
for the SCSI configuration in my Dell PowerEdge 1550.  I've attached the
relevant portions of the dmesgs (copied by hand) from the INSTALL kernels.
Note that 1.6_BETA4 kernel emits "generic HBA error" messages whereas the
1.5.3_RC2 kernel doesn't.  After a full installation of 1.6_BETA4, the
kernel panicked when the disks were heavily used during a data restore
procedure.  I unfortunately don't have a stack trace.  This machine was
previously quite stable running 1.5.3_RC2 as a file server.
