You told much but missed the most important point:
Whatever you call "2.6.22.1" isn't the vanilla 2.6.22.1 kernel from
ftp.kernel.org but the 2.6.22.1 kernel with a huge pile of external
drivers and/or patches, and therefore off-topic on this list.
Since your Oops involves unionfs that is not part of the 2.6.22.1 kernel
contacting the unionfs developers might be a good starting point for you
for looking for help.

"Is there not promise of rain?" Ling Tan asked suddenly out
of the darkness. There had been need of rain for many days.
"Only a promise," Lao Er said.
