I am running kernel 2.6.9-gentoo-r10 on an Athlon XP 2400+ computer with a SiI 3114 SATA controller hosting 4 WD2500JD-00G drives. I have combined these drives into a raid5 array using software raid, but unfortunately the array is not stable. I have tried several filesystems (ext3, reiserfs, xfs), but after copying several gigabytes of data into the array (using scp) and then trying to read them back (using rsync to compare over the network) always results in data corruption. Here is the output from 'dmesg':

kernel BUG at drivers/md/raid5.c:813!

Have you a bios option called ext-p2p discard time? Try setting it higher. I posted another thread about sii3112 at lkml about this issue...
