Stock driver in 2.6.11 or 2.6.12 cause hangs (crashes ?) too, but no kern= el mesages are logged on disk. I think this is crashing in cache_grow() (slab code), not sure because I = dont have access to the console. The 2.6.13-rc1 tg3 driver seems to survive (running for 18 hours now), an= d the cpu used by network activity was cut down :) rx-usecs: 500 rx-frames: 30 rx-usecs-irq: 500 rx-frames-irq: 20 tx-usecs: 490 tx-frames: 53 tx-usecs-irq: 490 tx-frames-irq: 5 About 1200 IRQ/second now, with 30000 recv packs/s and 25000 xmit pack/s Thank you Eric
