Are you running linux on there, or some other OS?  It sounds like the
usual "remount-readonly on filesystem corruption, instead of panicking"
linux behaviour, which (pretty much by definition) is a kernel (or
hardware) bug.

If that's the case, running dmesg or otherwise looking at the kernel
console output should show you; likewise "mount" (or cat /proc/mounts)
should show that it's read only (and fsck should probably end up doing
some work at reboot time to clean it up...)
