The patch below does not work for me. My 3c590 still falls off
the network during fairly heavy load when I apply it against 2.0.7.

Applying Ove's earlier patch (disabling the optimization altogether)
resulted in

eth0: 3Com 3c590 Vortex 10Mbps at 0x6000, 00:a0:24:57:ee:81, IRQ 10
Internal config register is 120010, transceivers 0xe138.
8K byte-wide RAM 1:1 Rx:Tx split, 10Mbs AUI interface.
3c59x.c:v0.25 5/17/96 becker@cesdis.gsfc.nasa.gov
[...]

eth0: vortex_open() InternalConfig 00120010.
eth0: vortex_open() irq 10 media status 0800.

and about four minutes later:

eth0: Infinite loop in interrupt, status e011. Disabling functions (78ee).
