Yes, I can confirm that!

As soon as I run a long "du -s" in background the flists start losing lines
or getting new ones. Besides wrong md5 checksums I got the following
errors:

awk: trying to access out of range field -1

awk: out of space in makefields 4160740

Then I made a second test with running a Whetstone benchmark in background.
The problem is less frequent here (maybe 2 or 3 flists out of 10), but it
can still be reproduced! So I hope it has nothing to do with DMA or a disk
driver.

For comparison: I was running on an A3000 with CSPPC 68060/50, 128MB, using
a disk attached to cbiiisc(4).

I could not reproduce it on i386 or macppc.
