Can someone tell me why some "Begin" entries in this SCSI fdisk
table _seem_ to have mutated to 1024? I am almost sure they didn't start
life that way.

   Device    Boot   Begin    Start      End   Blocks   Id  System

In contrast, dev/sdb on the same machien, which is rarely mounted,
seems quite sane:

I have seen the same effect but worse on an SMP dual PP200 (AIR FX440 ?)
with an onboard aic7880 running ultrawide and that machine is clearly
unstable so I am a little worried.  Is this something to worry about?
Or is it normal.  Firmware incompatibility or what?

Kernel is 2.0.25.  Thansk for any info, good or bad!!!  Bootup nmesage
follows.
