Hi List, I've run into an issue trying to install a new PowerEdge R720 server that arrived this week. It is equipped with a broadcom 5720 quad port network interface daughter card. I installed wheezy on it. No problems! The network interface works, and does not require any non-free firmware. Then I installed a xen kernel, and because of that update-initramfs was ran. I noticed these warnings: root@server:~# update-initramfs -uk all update-initramfs: Generating /boot/initrd.img-3.2.0-4-amd64 W: Possible missing firmware /lib/firmware/tigon/tg3_tso5.bin for module tg3 W: Possible missing firmware /lib/firmware/tigon/tg3_tso.bin for module tg3 W: Possible missing firmware /lib/firmware/tigon/tg3.bin for module tg3 These files are listed in the firmware-linux-nonfree package description for squeeze, I thought I'd give this package a try and install it. From that moment on eth0 is not working anymore. I get these kernel messages: [ 1796.583881] tg3 0000:01:00.0: eth0: transmit timed out, resetting [ 1797.840909] tg3 0000:01:00.0: eth0: 0x00000000: 0x165f14e4, 0x00100406, 0x02000000, 0x00800010 [ 1797.841066] tg3 0000:01:00.0: eth0: 0x00000010: 0xd91a000c, 0x00000000, 0xd91b000c, 0x00000000 ....

I booted back into the machine, purged the firmware-linux-nonfree package and am currently using eth1, that is still working: [ 1856.825856] tg3 0000:01:00.1: eth1: Link is up at 1000 Mbps, full duplex Now what happened? My *guess* is that the Broadcom 5720 for some reason is detected as one of these cards * Broadcom BCM5703/BCM5704 TSO firmware for tigon/tg3_tso.bin) * Broadcom BCM5701A0 firmware (tigon/tg3.bin) * Broadcom BCM5705 TSO firmware (tigon/tg3_tso5.bin) Then it loads that firmware blob onto the network card, breaking it. And now what? I have a bricked eth0. I really like to repair before the machine goes into production. Suggestions anyone? Should a debian package be fixed? It appears that the Broadcom 5720 does not need a firmware blob to operate. http://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/tigon has the same files as the firmware-linux-nonfree package plus one added 7 days ago for '57766 cards'. So nothing important there. There must be some code somewhere that decides what firmware to use. Possibly the tg3.ko driver in linux-image-3.2.0-4-amd64? Hope you can help me and avoid more broken Broadcom 5720's. Greetings, Casper |
