Severity: 3-Major

Symptoms

The HSB may drop off of the PCI bus. This results failure to read the HSB registers, which is indicated by the following log entries in the tmm logfile: Device error: hsb_lbb1 hde1_crc_errs count 65535. Device error: hsb_lbb1 hde2_crc_errs count 65535. This is usually followed by SIGABRT. The subsequent TMM reload fails to load the HSB device. Querying the PCI bus (using lspci), shows that the HSB device is unavailable: 03:00.0 Ethernet controller: F5 Networks Inc. Device 0006 (rev ff) (prog-if ff) !!! Unknown header type 7f
