Jarek,

Yes I am using n2kpci/8390 driver.
The second patch seems to have removed the inconsistent lock state.
But the kernel panic still occured systematically.
However I did not catch netconsole messages since the patch prevented 
transmission to remote console via ethernet.

Before the machine rebooted I only noted the following information at 
the bottom of the local console page :

EIP: [<.....>] datagram_poll + 0xe9/0xf0

Does it help ?

Bernard
