Subjectpossible bug with RAID

I have this pc with a promise udma133 tx2 controller, having one 120G
drive per channel. I'm benchmarking this, using some 50 'dd if=file[1..50]
of=/dev/null' to simuate my application. This will work for a few seconds,
giving me pretty good i/o speed, but then all the processes go defunct and
stay like that some minutes (i really don't know how long).

I tried to do the bechmark with the individual drives, and no problem

Anyone have a clue?

- Promise 133 TX2 (20269 manually patched in. Just made som defines to
alias it to the 20268)
- 2 WD1200BB drives (hde and hdg)


raiddev /dev/md0
raid-level 0
nr-raid-disks 2
persistent-superblock 0
chunk-size 4096

device /dev/hde
raid-disk 0
device /dev/hdg
raid-disk 1
