Hotplug oops with 2.6.7

[Federico Gherardini]

Hi all,

Sometimes, not always, I get this oops when I boot my computer, right before INIT starts. The machine completely hangs and the only solution is to turn off the power and reboot. Kernel is 2.6.7-ck5, call trace copied by hand

printing eip: c01ed578
*pde = 00000000
oops = 0000[#1]
PREEMPT SMP

eip is at devfs_d_revalidate_wait + 0xc8/0x223
Process default.hotplug (pid:205, threadinfo = df5a0000, task=df7406c0)

Call trace

This is on a Toshiba Satellite P10 with a 3 Ghz P4 with HT, here's my configuration, my .config is attached
