dd does not work anymore.
dd if=/dev/sda of=/dev/sdb bs=1024k
stops with "File size limit exceeded"
Using kernel 2.4.3 the same command works fine.
2.4.3 uses a large amount of buffer, 2.4.11p4 only chache.
2.4.3 doesn't swap, 2.4.11p4 eats up 1 GB RAM and 100 MB swap.

Block devices are handled by the page cache in 2.4.10 and up.

This is a bug in pre4. Please try pre5 instead!

Eh, did I miss something? Thought, that meta data are still
cached in buffer cache? Did it change from 2.4.9 to 2.4.10?
What about the ac kernels?

Yes.

FSes still use the buffer cache, but the block devices now use page cache.

Yes, in 2.4.10pre11

Block devices use Buffer Cache. Alan has stated that he doesn't plan to
merge this change any time soon, if at all.

Please try 2.4.11-pre5.
pre4 is seriously broken regarding high vm loads.
