SMP system?  What platform and 570x chip revision?

Does the stock driver in 2.6.12 hang as well?


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

Eric
