rootfs not found on rx-51 (Nokia N900)
Building pmos for the rx-51, and installing it to an sdcard (./pmbootstrap install --sdcard /dev/sdX) results in a kernel panic due to the kernel not being able to find a root filesystem (see screenshot)
My N900 is using u-boot from here: http://maemo.org/downloads/product/Maemo5/u-boot-flasher/
Sorry for the fuzzy photo, the watchdog timer on the N900 reboots the device fairly soon after the kernel panics, so I had to be fast.
