Bruno, will you explain your situation, environment, configuration,
etc. first?
Last month, you have reported that removing some files under
nfs_server:/var/cache/man caused nfs client locked. Is this firefox lock
problem related to nfs_server:/var/cache/man?

And where? I mean which function?


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

Do you mean that SysRq-A showed this line?
I can't believe it.

If "aufs_readpage:716: ... enter" is appeared, then it means careless
editing-miss was left somewhere in source files or memory corruption
occured.

How about serial-console or net-console to get logs?
