Ok,
I continue geting this problem, even with 2.6.24.5 and aufs-20080421

At console i could get SyReq W (blocked tasks) and A (aufs).

-blocked i could see a firefox in D state

-Aufs i got an infinite loop displaying:
aufs aufs_readpage:716:firefox-bin[2134] enter

Interesting that yesterday machine was displaying SAME message (only PID
changed). Same readpage!

We could not login and ALL logs were not beeing recorded.
