SubjectRe: Kernel 2.6.10-rc2 panic(?) -> reboots with certain options enabled. (fwd)
Problem found!

It is PnP support, it causes the machine to reboot itself.

In 2.6.10-rc2-5, I turned off:

1) all usb
2) all parallel port support
3) all pnp support

(PROBLEM FIXED)

--------------------------------------------------
Now to pinpoint problem.
--------------------------------------------------

In build 2.6.10-rc2-6, I turned on:
1) usb support

(STILL NO PROBLEM)

--------------------------------------------------

In build 2.6.10-rc2-7, I turned on:
2) all parallel port support

(STILL NO PROBEM) (of course its the last option right..)

--------------------------------------------------

3) enabled the following pnp options 1 at a time:

In build 2.6.10-rc2-8, I turned on:
x x [*] Plug and Play support x x

*** THIS IS THE CULPRIT

Kernel 2.6.10-rc2 build 8 w/ this option causes the machine to reboot
after it tries to load this kernel.
