That's fairly normal - at least I haven't been 
able to make the spin_lock's go away on my 
machine. Even when tweaking SRMMU_NOCACHE_ALCRATIO, 
it usually will crash after a few days (often 
less than a day)...

There seem to have been some fixes in the last 
2.4.21-rc's, but 2.4.21-rc8 has only been running 
for about 6 hours here now, so I can't tell yet if 
there's any improvement...
