NIC Tx Engine hang is a rarely occurring issue for which there are no known scenarios. In cases in which it occurs, an adapter reset is required to recover the system without reboot. The driver is currently not resetting the adapter, and the issue remains until reboot of system.
Traffic loss and overall system functionality is impacted, which sometimes it leads to kernel panic.
-- Running BIG-IP Virtual Edition (VE). -- No specific conditions. This is a rarely occurring issue.
No known workaround. You must reboot VE could recover the interface to normal functioning.
