The first time I ran md5sum on the file (on the share) was:

I rebooted the system, and this time it was:
2a93d60a45712595b6edbbfad5075de3 backup_ams_1.tar.gz

Testing the file with gzip gives this:

gzip -t -v backup_ams_1.tar.gz
backup_ams_1.tar.gz:
gzip: backup_ams_1.tar.gz: invalid compressed data--crc error

gzip: backup_ams_1.tar.gz: invalid compressed data--length error

The other two systems show the file is ok (file still on share)

gzip -t -v backup_ams_1.tar.gz
backup_ams_1.tar.gz: OK
On the Core 2 Duo machine is the kernel seeing it as two processors
or one. cat /proc/cpuinfo

It it is seeing it as two, try
taskset 0x00000001 gzip -t -v backup_ams_1.tar.gz

It would be interesting it was a core 2 duo problem with 9.3
I have seen one other very minor error when 9.3 could sense two cores
but it only exhibited itself in some video processing (MythTV stuff).

I have smp running:

orbit:~ # cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 15
model : 4
model name : Intel(R) Pentium(R) D CPU 3.20GHz

processor : 1
vendor_id : GenuineIntel
cpu family : 15
model : 4
model name : Intel(R) Pentium(R) D CPU 3.20GHz


orbit:~ # taskset 0x00000001 gzip -t -v backup_ams_1.tar.gz
backup_ams_1.tar.gz:
gzip: backup_ams_1.tar.gz: invalid compressed data--crc error

Herman Knief mentioned a similar problem with a nic, I am going to swap
it and see if that makes a difference.

Ok, swapped the nic and that solved the problem of bad md5sum/file
corruption. However, whey trying to copy the file from the network the
system locked up, could still ping, but no access to the box. System
console had this error:

ata1(0) WARNING: zero len r/w req

Could this be another issue, hard drive as well?
