With a bk tree current as of 7am Aug 1, I am getting repeated:

Sometimes a see a few per minute, other time 20 minutes may pass between occurances.

Only extra patch(s) applied are the floppy fix for 2.2.27 and a verson of slablru for 2.5.

Ideas?

1. bad: schedule() with irqs disabled!

Hey guys,

got this one on my Inspiron 2500 - and still can`t see
a fix in Linus` bk-tree. Do people agree that do_softirq() is
the bad guy ? Anyone looking into this ? I haven`t got the time
right now as I am both trying to figure out the qlogicisp.c mess
and trying to get a working i81x framebuffer in 2.5.33. But I do
think it is time we get it fixed.
