I experience an unhandled fault on reboot/shutdown using the ARM-OMAP kernel-2.6.41.3-1 and later (from Fedora) on a Panda Board. I have logged a bug in:

https://bugzilla.redhat.com/show_bug.cgi?id=781552

which provides the details, and a work around which reverts one commit from kernel-3.1.3.

Please let me know if you require any additional information or have changes for me to try.

Thank you,

That commit that you referenced in your bug report -- which is actually mainline commit af8db1508f2c9f3b6e633e2d2d906c6557c617f9 ("PM / driver
core: disable device's runtime PM during shutdown") -- is broken.

Consider leaving it reverted or backporting Alan Stern's commit fe6b91f47080eb17d21cbf2a39311877d57f6938 ("PM / Driver core: leave runtime PM enabled during system shutdown").

Thank you for the information. We will leave this one reverted for now, and catch Alan Stern's commit in the next version.

Thanks again,
