Stock driver in 2.6.11 or 2.6.12 cause hangs (crashes ?) too, but no kernel 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), and 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
