Description:
On an otherwise up-to-date arch system (i686, fitpc2, Intel Atom Z510), running kernel 2.6.39.1-1, reboot (and "shutdown -r") do not work and simply hang.

"shutdown -h" still works fine, and powers down as expected here.

Downgrading just the kernel26 package to 2.6.38.7-1 (happened to be my prior version) and reboot works again.

fitpc2 uses BIOS reboot. Initially I suspected this bug: https://bugzilla.kernel.org/show_bug.cgi?id=33302
however that is marked closed and should therefore already be in 2.6.39 (and presumably 2.6.39.1 also)

Originally reported on forums here, before I found the archlinux flyspray:

This task depends upon

Clarification: with kernel 2.6.39.1-1 , reboot (and "shutdown -r") carry out the shutdown process fine, but merely hang indefinitely at the point where they should restart the system. Interactive users just see the broadcast message telling them that the system is about to restart but it doesn't. Processes are shut down at that point: screen is active with blinking cursor, but cannot login over ssh etc.

With kernel 2.6.38.7-1 , the system reboots as expected .

Note that I've also raised this as an issue on kernel.org too but only because I don't know if the issue is on the vanilla kernel or on the Arch (patched) version. I'm using the kernel26 arch package (i.e. I am not using kernel26-vanilla).

According to this forum, it's not just fit-pc2. Thanks. I don't know if you want to rename this back to how it was or not.

I have separately confirmed that the problem still persists on 2.6.39.1-vanilla i.e. kernel built from AUR package without ARCH-specific patches. This suggests to me that this must just be an upstream kernel bug (assuming the AUR kernel26-vanilla package is indeed entirely vanilla).

This is also present on 2.6.39.2 and 2.6.39.3 kernels. I don't know if it's worth tracking this on bugs.archlinux.org or not, but nobody seems to be interested in this bug (neither on bugs.archlinux.org nor bugzilla.kernel.org)

Still present on the 3.0 kernel that just hit Core.

still present on the new kernels too as far as I can tell.
I raised a bugzilla issue (before kernel.org went down...) - anyone know if the linux kernel folks still look at bug reports??
