Subjectinit_dev accesses out-of-bounds tty index
Date
(nvidia) tainted kernel warning so you may wish to stop reading here.

I've tried to just raise a bug (my first), but I get this every time:

> Bugzilla has suffered an internal error. Please save this page and send it
to THE MAINTAINER HAS NOT YET BEEN SET with details of what you were doing
at the time this message appeared.
> URL: http://bugzilla.kernel.org/post_bug.cgi
> A legal Architecture was not set.

I couldn't see any Architecture field for me to fill out. So I'll revert to
using a FAQ proforma:

[1.] One line summary of the problem:

init_dev accesses out-of-bounds tty index

[2.] Full description of the problem/report:

Much like http://www.ussg.iu.edu/hypermail/linux/kernel/0310.1/0741.html I
got an oops and then seemingly couldn't fork new processes. I couldn't
login and Ctrl-Alt-Del from the console didn't reboot. This has happened
three times now in the week since I upgraded from a 2.4 kernel to 2.6.2 (and
never happened before) so I figured it might be worth reporting even though
the kernel is tainted by nvidia.

This seems to be the repeatable stack:

I've not much idea.

I've not yet found the necessary incantation to make /proc/ksyms spring into
existence for the benefit of ksymoops but I did some disassembly on one of
the earlier instances:
