mount -t ext2 /dev/sda1 /mnt does not returnHave you tried mounting it read-only? Also, can you tell where the mount process is hung? Try Alt-SysRq-T (and make sure you have enabled the Magic SysRq key in your kernel).
Since my system is an embedded platform without keyboard, I can only post a strace output from the mount command. As you can see, the call blocks in the open systemcall on the /dev/sda1 device.
When I interrupt the strace/mount with CTRL-C the open() call is interrupted unfinished. Without strace the mount call cannot be interrupted by CTRL-C.
bash-2.05# strace /root/mount -t auto /dev/sda1 /mnt
