halt & reboot: segfaulting

[Andreas Jaehnigen <jaehnias@IMS.Uni-Stuttgart.DE>]

Hi there,

I'm running "Slink" on an SLC with 16 megs RAM. The machine boots via tftp and
gets its filesystems via NFS from a server running Sun Solaris 2.6
Everything is is fine, but a few days ago I noticed that "reboot" and "halt"
won't work. If I run a system on a hard disk, everything is fine.
Here's the strace output from "reboot" (shortened):

...

Segmentation fault

Any clues???

Thanks in advance for any hints given! :-)
