Hello,
I have a Dell Inspiron 8600, with the integrated bluetooth module, which
I see as usb device. I run gentoo, kernel 2.6.7-gentoo-r11
(sys-kernel/gentoo-dev-sources).
lspci -v -v -v result is attached, the full boot log as well.
I can enable/disable the wireless parts (bluetooth and IPW2200 mini-pci
card) using a hotkey (Fn-F2). A blue led shows the status.
If I boot with it disabled (eg I hotkey it to off during grub
countdown), and I enable it afterwards, everything is OK, I can use
bluez with hci and friends fine.
If I boot it with the wireless stuff enabled, I get a sort of oops,
below is the partial log, see attachment for unwrapped log.
I suspect either bluez or USB subsystems, but you guys will probably be
able to help me. The whole things appeared a few kernel version ago, but
I can reproduce this history. Thanks for hints.
Regards,
Charles

Hi Marcel and list,
thanks for your hint. After 3 cold boots with wireless "on", no Oops to
report. However, I'm now running the vanilla 2.6.9rc2, and my bug was
previously happening under gentoo-dev-sources, which is heavily
patched.
I will have to wait for gentoo-dev-sources-2.6.9 to see if the bug is
really gone.
Meanwhile, I like the boot without stack dumps. Thanks for your support
!
Regards,
Charles

please check out 2.6.9-rc2 and also try if disabling preempt helps.
