I think you had a different issue. I am using reiserfs like the original
poster (I like to be able to resize lvms down), and I see a delete pause of
1-2 seconds, no lockups or anything.

However, I can induce a hard lockup on my box very easily. If I run a very
data intensive process I _will_ get a hard lockup. I have moved commercial
detection to my slave backend beacuse every 2-3 months I will get a hard
lockup if I have a lot of commercial detection jobs running. Transcoding
also causes issues. Of course I have an nforce2 chipset and I believe that
it is the root of the problem. The only solace I can give you is that I have
managed to configure my box to have really good uptime by keeping the large
intensive jobs on the slave.
