OK, I am starting a new thread here, as the other was getting unwieldy.
This one is 100% reproducible, happens immediately when I start JACK. I
have set CONFIG_FRAME_POINTER=y and CONFIG_4KSTACKS=n as you requested.

OK, I'll fix get_user_pages().

I have copied my system onto an ext3 filesystem and ran the same test.
It seems to be much better. These are all the XRUNs from running my
JACK test while untarring a kernel tree in /tmp while doing `find /
-ls'. There are not too many. Previously I had to send excerpts, this
is the entire log. With reiserfs, I was not having to artificially
stress the filesystem at all to produce WAY more XRUN traces than this.

With 2.6.8-rc1-mm1, when I have started a jackd process in the playback
direction, and launch another in the capture direction, I can reliably
trigger a ~150ms XRUN in the first process. The duration of the XRUN
is exactly the same each time, it is probably a funciton of the amount
of memory being mlockall()'ed.
Otherwise this kernel seems pretty good.

I am also getting this one. This is with 2.6.8-rc1-mm1 + La Monte H.P.

After removing (un)lock_kernel from do_tty_write, I can still cause an
XRUN by switching consoles, but it it much less common that before. I
have not seen any display problems at all.
