Subjectcrash and tcp messages [2.1.96]

Two items:

1. I had a crash a few days ago...I was copying a 600+ meg directory
tree from a IDE drive over to a SCSI drive. I was using:
tar cvf - | ( cd /otherdir/on/scsi/drive; tar xf -)

Machine got about 200meg into the transfer and appeared to lock. I
was able to use Magic SysRq to reboot.

The only thing in my logs after I came back up was:

Apr 18 14:18:54 jelerak kernel: SCSI disk error : host 0 channel 0 id 4 lun 0 return code = 2505007f
Apr 18 14:18:54 jelerak kernel: scsidisk I/O error: dev 08:11, sector 354920

after I came back up, I removed the partial tree and did:
cp -r /old/ide/dir /new/scsi/dir
and it worked fine.

2. I have some tcp debug message in my dmesg output:

I know davem has commented on the bad checksum errors before being
likely due to bad vj compression. I am on the net via a Symplex ISDN
router and dont see any problems. Would I see these errors with bad vj
on the other side of the connection? Also, why are they in reverse
order (ie, my machine, the "to" is really 207.174.18.194, not the
reverse).

I have never seen the icmp messages before.

My config:

Tyan tempest II with 2 p166's in it. 2.1.96 + alan cox'es fix for the
latest tcp DOS attack.
