Well, not much of info, really.. ;)

Here it is. From HP ML 150 box. I compiled 2.6.11-rc6 with the patch you've sent.

[at this point, modprobe is stuck, with `_stext' (it seems) in /proc/$modprobe_pid/wchan, eating 100% of one CPU, with another fair load from migration/0 and events/0 threads. strace on it gets stuck too.]
I can try 2.6.11 too. I'm a bit afraid to try this on HP ML 310 box for now - this HPML150 seems to have rebooted nicely without any bad things, but if that HPML310 (production) machine will not come back automatically, it'll be a bit of a problem.. ;)
