We have also been seeing watchdog timeouts with bnx2, below is a stack trace with Benjamin's debug patch applied. Normally we were only seeing them under heavy load, but this one was at boot. We haven't tried the latest firmware/driver from 2.6.33 yet. You can contact me offline if you need more detailed info.
