I'm having severe interactivity problems with 2.6 tree on a dual Athlon system.
I mostly get 'X screen freezes/mouse pointer immovable for a several
seconds' and rather often audio skips.
I can't really pinpoint it on some activity, but I can trigger this easily
just by switching working desktops. Applications I use are not really
anything special (sorted by virtual memory usage):

Most degenerate case comes however when _closing_ some application,
especially if it has been dropped into swap. Below is 'vmstat 1' of my
shutting down (swapped-out) GIMP2.0 after I load some other memory-hungry
applications. 'freeze' and 'unfreeze' mark points at which vmstats
output really comes onto terminal.
-I really pushed 'close' on GIMP half-a minute earlier-

I've also wondered a bit about slabtop, is this really OK for half-a-day
uptime and not really changing since?:
OBJS ACTIVE USE OBJ SIZE SLABS OBJ/SLAB CACHE SIZE NAME
348220 348135 99% 0.19K 17411 20 69644K dentry_cache
313138 313049 99% 0.50K 44734 7 178936K ext3_inode_cache
10530 7354 69% 0.05K 135 78 540K buffer_head
This machine is rather standard 2xAthlon/512MB, 1G swap/UDMA2 disk.
Is there anything I can do to help solve this?
Thanks.
