I have applied the 1594 patch to support an Adaptec 2842 VL-Bus SCSI2
controller.  It seems to operate okay until I reboot.  The NetBSD loader doesn't
get past the first spinning '/' and then a hard reset is done.  I have fsck'd
my root partion '/dev/sd0a' and it reports 'CPG OUT OF RANGE' followed by a
invalid block count.  I can then boot off of the drive in question, but upon a
reboot, 'KA-BOOM'.  It seems to do this every time I reboot. 

The machine is a Micronics JX30Gc with an 83 Mhz Pentium OverDrive chip 2 VL
and 5 ISA slots.  It has 32MB RAM, Adaptec 2842 Bus-Mastering SCSI controller,
and a Diamond Stealth 24 VL-Bus graphics card with 1MB.

My fstab looks like the following:

/dev/sd0a        /          ffs    rw           1 1
/dev/sd0b        none       swap   sw           0 0

/etc/portal.conf /p         portal rw           0 0
/dev/sd1e        /usr       ffs    rw           1 2
/dev/sd0f        /usr/src   ffs    rw           1 2
/dev/sd1f        /var       ffs    rw           1 2
/dev/sd0e        /var/users ffs   rw            1 2
/dev/cd0a        /cdrom     cd9660 ro,noauto    0 0

Any help/suggestions would be appreciated.
