Start transcode in one window, doing something like:
"transcode -i /dev/hdc -x dvd -U file_name -y divx4"
on a DVD ... probably pretty CPU intensive as well as IO.
Now do ls in another window ... hangs for about 5 seconds before
giving any output ;-( Anyone else seeing that? I do get a lot of
"*** libdvdread: CHECK_VALUE failed in nav_read.c:202 ***"
messages as well ... but I always seem to get those from DVD stuff.
All IDE, 2.6.0-rc1.

DMA or PIO? vmstat info would be very handy here.

OK, now I'm really confused ... sometimes it happens. sometimes it doesn't
with no apparent rhyme or reason. You're welcome to the data I have though.
titus:~# hdparm /dev/hda (the hard disk)
/dev/hda:
multcount = 16 (on)
I/O support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 256 (on)
geometry = 58168/16/63, sectors = 58633344, start = 0
busstate = 1 (on)
titus:~# hdparm /dev/hdc (the DVD drive)
/dev/hdc:
HDIO_GET_MULTCOUNT failed: Invalid argument
I/O support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
HDIO_GET_NOWERR failed: Invalid argument
readonly = 1 (on)
readahead = 8 (on)
HDIO_GETGEO failed: Invalid argument
busstate = 1 (on)
readahead was 256 on the DVD last night when I was having problems,
and ls -l on the same directory was repeatedly hanging ... now seems
to be just on new directories, that it'd have to go to disk for, presumably.
Switched it back to 256 again ... get a 12s hang doing an ls -l on
a dir with only 10 entries in it ... hang is about 120s on a directory
with 50 entries ;-(
Switch it back to 8 ... can now do an ls -l of a directory with 7000
entries in < 0.5s.
Switch it back to 256 again ... all seems to be fine again ... WTF?
MemFree: 115840 kB .... wait until
(readahed = 8)

You have periods of excessive system usage, although DMA is enabled on
the drive. Depending on what transcode does, it might still be using pio
though. Any chance you can profile such a 'sy' peak so we can see what's
going on?
Looks odds, though. I'm inclined to guess this is a CPU scheduler
problem. Does booting with elevator=deadline change anything at all?

OK, here's a capture of data from when the system is being a little bit
slow to respond, though nothing as bad as I'd managed to recreate earlier.
There's a vmstat 5, mixed with a grab of some fields from /proc/meminfo,
and the dentry_cache from slabinfo (every 5 seconds).
