Hi,

Well, I've  begun to work with Fedora again to get  my Linksys  
WPC54GX working. This time, I wanted to try the Linuxant DriverLoader.

I downloaded and installed the Linuxant 2.6.12-1.388_FC4.stk16 kernel  
to address the 4 k stack problem. Upon reboot, I encountered a kernel  
panic:

"Kernel panic - not syncing: net/sched ... generic.c:547:  
spin_is_locked on uninitialized spinlock df4f3170. (Not tainted)"

Two questions: what may have caused this and which kernel version do  
I install? i586 or i686? How do I know which is the right one?

Finally, any hints about restoring the previous kernel would be helpful.

Thanks,
Paul Hoy
