raid5 resync 2.6.10 freez

[Axel Christiansen <axel@zedx.org>]

Hello,

i recently upgraded to a 4-IDE-RAID5. Since than the array
is not able to resync itself.

linux 2.6.10 with software-raid
mdadm - v1.5.0 - 22 Jan 2004
4 X IDE DISK WDC WD1600JB-00FUA0 (160 GB)
2 X HPT374 (rev 07) IDE Conroller
Epox 8K5-A3+
Duron 1500 MHz CPU

After 5 to 10 minutes the os freez. The system console does
not show anything.

I tried some 20 Kernels with no success.
Regardless of the resync speed the system freezes
sooner ar later.

10000 Kb/s after some 10 minutes.
1000  Kb/s after 1 to 2 hours.

There is no filesystem involved. The degraded arry without
resyncing works fine.

How do i fugure out whats going on.

Thanks, Axel
