--- Comment #3 from Teran McKinney <sega01@go-beyond.org> ---
Thanks for replying.

I have only had this happen with EXT2, EXT3, or EXT4. No other filesystem I=
've
tested. FFS, ZFS, and are fine, likely FAT as well.

This is from a Beagleboard. I believe x86_64 gives similar Translation Fault
panics.
