Now for the problem. I used fdisk to remove the msdos partitions on sda and
sdb and then created ext2 ones. Then I ran mke2fs on them both at same time
on diferent pages. Said behavior didn't occur under 2.0.27 (I skipped
2.0.28 and 2.0.29)

I've seen similar messages for quite a while, but the changes to buffer.c in
2.0.30 do seem to make them more common. I'm fairly sure that some work is
still needed in 2.0.30+ to be more agressive in making memory available to the
kernel when necessary.
