[DragonFlyBSD - Bug #2518] mounting devfs at boot hangs on at least two i386 machines

[David Shao via Redmine <bugtracker-admin@xxxxxxxxxxxxxxxxxxxxx>]

Issue #2518 has been updated by davshao.


Thanks to the recommendation to mv / delete /include on

http://bugs.dragonflybsd.org/issues/2505

I have been able to switch all of my machines to use the default gcc 4.7 for everything.

However I have also been able to reproduce the hang after

Mounting devfs

on multiple machines running i386.

It appears on i386 there may be a regression after

commit 79fd1696254e1413ba2bd0b0c029e2acd9ba416a
Date:   Fri Feb 22 21:57:45 2013 -0800

    kernel - Implement shared namecache locks

and possibly including

commit 1327cb0bd0b371b2d8c86c95cf0f6c84880b215b
Date:   Sat Feb 23 11:49:31 2013 -0800

    debug - vmpageinfo changes

that results in booting hanging at

mounting devfs

Attached is a dmesg of one of the machines.  So far this has been tested on an Intel and an AMD64 machine that could run x86_64 but for which I also have a partition running i386.

I am compiling world and kernel using

# make -j7 buildworld && make CCVER=gcc44 buildkernel
