I'd be suspecting there's been a huge preempt_count() windup and the kernel
thinks that it's running in_interrupt(), so various checks are triggering.
Please try this one:
--- devel/net/netlink/af_netlink.c~netlink-locking-fix 2005-07-27 14:10:07.000000000 -0700
+++ devel-akpm/net/netlink/af_netlink.c 2005-07-27 14:10:16.000000000 -0700
@@ -349,12 +349,12 @@ static int netlink_create(struct socket
netlink_table_grab();
if (!nl_table[protocol].hash.entries) {
- netlink_table_ungrab();
#ifdef CONFIG_KMOD
/* We do 'best effort'. If we find a matching module,
* it is loaded. If not, we don't return an error to
* allow pure userspace<->userspace communication. -HW
*/
+ netlink_table_ungrab();
request_module("net-pf-%d-proto-%d", PF_NETLINK, protocol);
netlink_table_grab();
#endif
_
And if that doesn't fix, enable CONFIG_DEBUG_PREEMPT and see if the
sub_preempt_count() check triggers.
