Subject2.5.70-mm2, modprobe mga oops, modutils hangs -> machine unbootable
Hi!
Running 2.7.70-mm2 (with two ext3 patches akpm posted), after starting
XFree86, which tries to modprobe mga I get an Oops (below). After that,
every single modutils command hangs. Attached is also 'strace modprobe mii'
(mii is compiled as module and not loaded on boot). strace was killable with
ctrl-c, but subsequent 'modprobe mii', wasn't.
