5 Known problems and limitations

The following problems and limitations are known to exist in this release:

• AD393A GbE SX Fiber ports fail (QXCR1001284665)

GbE links on the ports of an AD393A adapter fail at boot.

Severity: High

Workaround: This problem was introduced in the B.11.31.1209.01 release. Revert to

B.11.31.1209 (or earlier) until this issue is fixed for a future release.

• 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.
