This is usualy not a problem in ext2-fs. - And I think in raid, neither.
Something in 2.2.x was improved drastically, that my SCSI-adapter made
problems. I changed the external clock from 83 MHz back to 66 MHz and the
PCI-bus from async. 32 MHz to sync. 33 MHz.
Before that I could reproduce a system-stop with:
ls -flaR / &
cat /dev/sda > /dev/null &
cat /dev/sdb > /dev/null &
cat /dev/sdc > /dev/null &
cat /dev/sdd > /dev/null &
The update-daemon was also running. If this "heavy" SCSI-load corrupts
something, there could be a problem with the hardware.
Or maybe I'm completely wrong... (:
