Hi,
Using the 2.6.23.1 kernel and Debian Etch on a Lenovo Thinkpad T61

7659A21, I am getting two weird errors, as follows:

I have tried booting with the irqpoll option, but this results in the

automounter doing weird things with the optical drive. Specifically, it

sporadically mounts an audio disc with weird negative-sized tracks, even

if there is no disc inserted in the drive.
Also, regardless of whether I boot with irqpoll or not, chrony

frequently uses up 100% of one CPU. The chrony measurements.log,

statistics.log and tracking.log all show normal activity (ie: a "normal"

Turn off bluetooth and you may find the stuck IRQ goes away - at least on

some thinkpads there are weird extra IRQs when bluetooth is running which

break stuff.

There was an old American Music/Comedy show called "Hee Haw!" which had

a recurring skit consisting of a farmer running into the doctor's office

and saying

   "Doctor, doctor! It hurts when I do this!" followed by some unlikely

activity.

   The doctor always replied "Then don't do that."
Turning off bluetooth is a useful diagnostic test, but for some systems

it's not a practical operating configuration. Any thoughts on making

bluetooth work in these cases? Most laptops make a unit like the

Logitech MX5000 BT keyboard desirable for extended use.
