Hi, first the message I posted into the Gentoo-Forums: http://forums.gentoo.org/viewtopic-t-295168-start-250.html#4895168 Problem: On my computer I use Reiser4. When I try to access my computer via nfs from another computer I get a Kernel Ooops. I can still reboot the machine. But several things in a term don't work anymore without reboot. The nfs-server starts without problems on my computer. The error occures only when someony tries to access. The error is reproducible and occures always when try to access via nfs.
