I tried to burn a CD using this command-line in 2.6.0-test9-mm2:
sudo cdrecord -v dev="/dev/hdd" -dao -useinfo *.wav
Result:
[this about 5 times per second]

I'm seeing this as well burning an ISO in TAO mode on /dev/hdb, but slightly different traceback:

(pfkey_xfrm_state2msg()??? But I'm not doing ipsec - is the traceback on crack? ;)
In addition, I end up with a bad burn because *something* is managing to
starve off reading the ISO off disk and we get a buffer underrun.
Under earlier kernels (-test7 or so), the input buffer stayed around 90+%,
here it would start off near empty, get up to about 50%, then slowly go down
till it hit zero, got an underrun, and croaked. One CD got 9M in, another
got 38M in. Decided to wait till I had more blanks handy before debugging
more. (I admit not knowing if the problem is the AS elevator, or
Con's swappiness patch).
Yes, the source disk hda and target CD/RW hdb are on the same IDE
controller, blame Dell.. ;) (though it's worked fine for a year till now).

The as scheduler in test9-mm2 is a bit fubar, reboot after adding
"elevator=deadline" to the kernel options in grub.conf.
With the exception of an occasional ac97 message, the logs are now
clean, and the mouse is much smoother.
