Sorry, forgot that. I think 2.6.20.6 or 2.6.20.7 (I always rename them to .3,
for some reasons thats easier than to change our tftp-rembo config). The
kernel is patches with lustre patches, hmm, one of them also adds a read-only
test to the block device layer.
Probably I should test a vanilla kernel. Going to do that now...
Thanks,
Bernd
