To debug this a bit further:

$ od -a -t x1 -v init.after > init.after.dump
$ od -a -t x1 -v init.before > init.before.dump
$ diff -u init.before.dump init.after.dump | less
-0011340 nul nul nul e9 f0 fe ff ff ff % < soh enq bs h 80

The file at offset 0010000 - 0011348 is overwritten with the byte
pattern 79 06 00 00.
Do you see anything in the logs or is this a silent corruption? Did
you see this corruption with 2.6.19 or 2.6.22-rc3?
