>Description:
When using both ports on a PWLA8492MT adapter,

Oct  8 23:15:09 vpn1 kernel: em1: Unable to initialize the hardware

message appear, then network card does not work until reboot. But, if both ports are used it happening just after system boots up.

If only one port used network card works correctly.
