Hmm, I am seeing some breakage also.  The last working kernel I have is
from June 29.  My first broken kernel is from August 3.  In between I
didn't build a new kernel. :)

My breakage is that my external 1GB SCSI drive doesn't work correctly under
the new kernel.  If I dump the first 1MB from the disk under each kernel
they are not identical and under the newest kernel the disklabel is missing
and the data appears to be repeating or something odd.
My internal RZ23 drives work under the new kernel, but not the IBM.

My internal drive: (also sd1)
sd0 at scsibus0 target 2 lun 0: <DEC, RZ23     (C) DEC, 0A18> SCSI1 0/direct fixed
sd0: 100 MB, 776 cyl, 8 head, 33 sec, 512 bytes/sect x 204864 sectors

External drive:
sd3 at scsibus1 target 0 lun 0: <IBM, 0663L12, 1012> SCSI2 0/direct fixed
sd3: 1003 MB, 4119 cyl, 5 head, 99 sec, 512 bytes/sect x 2055035 sectors

Oddly this looks more like /usr (/dev/sd1e) than /u0 which has 'src' on it.

Something is fishy here.  I've rebuilt the kernel several times with no
change. (e.g. after removing the build directory)

This is on a VAXStation 3100/M38 with 24MB.
