Hmm, now after few ours of running mysql tests I have (while still running):
linux-2.4.10-pre12aa1
dbench 16: Throughput 41.1484 MB/sec (NB=51.4356 MB/sec 411.484 MBit/sec) 16 procs

Load so far up to 7 (yesterday even 16, but thatt dependes of course while
test is currently being run).

And, well oh NO!, it's here again:
__alloc_pages: 0-order allocation failed (gfp=0x20/0) from c012f852

How can I find what mean those (gfp=0x20/0) from c012f852 ?
