Symptoms

The HiGig MAC (HGM) registers are not dumped to the log files when an HSB transmitter failure occurs.

Impact

Only part of the log registered are dumped to the log files when an HSB transmitter failure occurs. The following HiGig event and HSB transmitter failure are present in the log files: -- info bcm56xxd[7746]: 012c0015:6: Link: 4.3 is DOWN -- info bcm56xxd[7746]: 012c0012:6: Reset HSBe2 (bus 1) HGM2 MAC completed on higig2 link 4.3 down event. -- info bcm56xxd[7746]: 012c0015:6: Link: 4.3 is UP -- crit tmm5[14718]: 01230111:2: Interface 0.6: HSB DMA lockup on transmitter failure.

Conditions

When an HSB transmitter failure occurs due to an issue in the HiGig MAC, there is not enough information in the log files to determine the cause of the lockup.

Workaround

None
