Ok, depending on the metadata load before the crash, replay can take 30
seconds or more.  You usually have to try to generate that many metadata
changes, something like creating 100,000 tiny files or directories.
Compiling with CONFIG_REISERFS_CHECK turned on will give you more details
about the log replay.

Or, perhaps DMA is now off on your IDE drive, making everything slower.

Regardless, rebooting in the middle of log replay is safe.  Those
transactions will just be replayed again on the next boot.
