Problem with kernel modules after upgrade FC2->FC3

[Dusan Djordjevic]

Hi all,

I upgraded my working FC2 to FC3. Mostly it works fine except one thing. 
When I try to compile some kernel modules (in my case it is module for 
modem) it compiles, loads and works perfectly. But when I reboot 
machine, it stops working. All modules are in right place 
(/lib/modules/2.6.9-1.667/extra/) but something is not working. When I 
try to start slmodemd (daemon that drives modem) won't load, and here 
is strace:

ice~>strace slmodemd

exit_group(-1)               

Something similar happens with vmware modules. 
Any idea ?
