Here are some more test results:
1. strace shows that bonnie++ fails in a write() function which returns
   "-1" which lets bonnie++ gracefully terminate. It even cleans up
   after itself by deleting the files it has created in the very same
   AFS partition it claims it cannot access.
2. During all bonnie++ runs I had a second xterm opened on the client
   machine. I could access ("/bin/ls -l") the directory bonnie++ was
   writing to all the time.
3. I had the AFS cache on the RH7.2 client on a ext3 partition. I changed
   that to ext2. Same bonnie++ failure.
4. I tried different bonnie++ parameters: "-s 1g -r 500M" instead of
   "-s 2g". Same failure.
5. Tried the same hardware but RedHat6.2 (2.2.19-6.2.7smp kernel) with
   OpenAFS-1.2.2. That works.
6. I ran some other (home grown) filesystem test from my RH7.2 client
   against the AFS filesystem. These tests are not really sophisticated.
   But none failed.

I am out of ideas what else to test/check/modify to get this working.

Thanks,
            Alf.
