Hello,

Ok, I have a goofy problem with an external IBM disk on my VS3100/M38.
With an older 1.5_ALPHA kernel (dmesg below) my external disk works fine
and has a valid disklabel.  With a fresh new 1.5_ALPHA2 kernel (dmesg
also below) the disklabel is not recognized.  If I attempt to write out
a new disklabel ("disklabel -r -R sd3 mylabel") it succeeds and appears
to be normal, until I reboot.  Then the label is gone.

So does anyone have any idea what changed WRT scsi on the VAX port
since June 29? :-)  I haven't tried checking out the code from July or
anything yet, I was hoping someone would have an idea what is going
wrong here.

The only odd thing I notice is the number of sectors reported by the
kernel don't match my disklabel, but I've tried it with the 2055035
number also.  The actual number should be 4119*5*99 which is what I
am using.

Thanks.

-Andrew
