We have a problem with Xenomai v2.4.9.1, kernel 2.6.31, x86 SMP in that we
get a kernel panic on reboot:
swapper[0]: segfault at 15aba ip 0000e6ba sp 00000189 error 4
no vm86_info: BAD
Kernel panic - not syncing: Attempted to kill the idle task!
Pis: 0, comm.: swapper Not tainted 2.6.31-CROCUS #1

Other than this, it seems to work fine.
We had previously been using v2.4.7, kernel 2.6.28.7 which does not have
this issue but for development, we would like to use X and we find that some
X applications (e.g. Netbeans & eclipse) hang the system (with no indication
of cause i.e. no console messages & nothing in the logs - the system just
stops). However, when we use v2.4.9.1 with kernel 2.6.31, we can use X apps
perfectly but we can't reboot!
Anyone have any ideas/suggestions?
