IEther-00 (iether) B.11.31.1303 Ethernet Driver Release Notes (2nd Edition)

and connected to an external switch, system panic might occur when external switch UP/DOWN
status changes
On NC364 or NC360 adapters, with APA aggregation configured on ports connected to an
external switch, when a user changes the external switch status from UP to DOWN or vice
versa, a system panic occurs. The following panic string is seen:
'wait_for_lock: Already owns lock: lan:iether_hw_lockp '
This occurs in rare circumstances and only on the specific adapters noted.
• Ethernet parameter restrictions
For PCI and PCI-X LAN adapters that use the iether driver, HP does not recommend changing
the default values of the following four tunables. It has been found that certain combinations
of these tunables (other than the default settings) could result in adapter hangs.
◦ send_max_bufs
◦ recv_max_bufs
◦ send_coal_ticks
◦ recv_coal_ticks
These tunables are not supported with PCI-E adapters that use the iether driver.
