Hey guys,

I am using three Myricom 10Gb Fibre PCI ethernet cards running on Redhat 5.4. lspci detects all three cards, but ifconfig -a only maps two out of the three cards, to eth2 and eth3 (eth0 and eth1 are my onboard gigabit ports). I have another server with the same configuration and ifconfig -a detects all three cards. I swapped all the cards on the first machine with all the cards from the working machine to see if it was the card that was broken, but the new card on the third slot is still not detected by the broken machine. Below is an excerpt of the dmesg.

Myri10ge: unable to load myri10ge_eth_z8e.dat firmware image via hotplug
Myri10ge: Hotplug firmware loading failed
Myri10ge: Successfully adopted running firmware
Myri10ge: Using firmware currently running on NIC. For optimal performance consider loading optimized firmware via hotplug
Myri10ge: Command 1 failed, result =14
Myri10ge: Failed reset
Myri10ge: Myri10ge_probe() failed
Myri10ge: PCI INT A disabled

I think the card is being detected on the PCI bus, but for some reason ifconfig is not assigning it to eth4 or eth-anything! Any suggestions?

I fixed this problem by doing the following (it may be one or all of the steps, but it worked for me):

1. Get the myri-tools package from the Myricom website (if you're on a 64bit system, you will need the libc6-i386 compatibility packages).
2. Update the firmware (a .mcp2 file)
3. Update the eeprom ("ze-upgrade-ee <filename>" I think, it's a file in the eeprom directory)
4. Reset NVRAM or PCI Config in BIOS to force reallocation of interrupts (I somewhat doubt this fixed it, but did it anyway)

My driver now loads swimmingly. If only I knew how to fix the firmware loading problem in Lucid!
