Hello Gerrit,

I tried to be more precise.

I run the same kernel in two very similar computers, in one computer
it works perfect, in another one, not. Maybe this problem is happening
due to miss-configuring in the computer that occurs this error. In all
the case, I have here de .config for both machines (kernel 2.6.27-rc8)
and the complete strace.log for both execution. If you'd like to
analyze them I can send you. Please let me know in case that you want
me to send you the configs and strace log files.

Regards,
Leandro.
