Software raid constantly out of sync

Description of problem:
I run Phoebe (8.0.93 and 8.0.94) on an athlon with three RAID1 partitions across
two drives. Everything run smoothly.
I upgraded that installation to Shrike a week ago. Ever since, my drives have
been crunching for long streches and the system log is full of messages like
Apr 13 21:18:41 pig kernel: raid1: raid set md2 not clean; reconstructing mirrors
This happened invariably after heavy write activity, like massive copying of
data, but sometimes also after moderate writing.
A rumour in IRC-land has it that kernel-2.4.20-8 can't manage the combination of
ext3 and software raid. I was not able to find any official RH confirmation, but
downgraded to kernel-2.4.18-14.athlon anyway.
The crunching is gone. The error messages are gone. Everything works smoothly
again. Heavy copying has no abnormal side-effects whatsoever. I can only draw
the conclusion that the problem was not in my hardware or configuration and that
the rumour is probably correct.
Version-Release number of selected component (if applicable):
Didn't try (fear loss of data)
