disconnected under load

[shpokas]

Hi!
great job, but two issues detected.
with BCM5787M (0x14e4,0x1693) connected to gigabit swich.

1. it doesn't work after sleep/wake;
2. it disconnects under load.

Typically a few gigabytes can be copied and then it stops. Interface still up, IP address assigned, but cannot be pinged or anything.
No error messages in system.log or kernel.log or dmesg output.
Kext unloading/loading fixes this. Simple cable disconnection/connection or ifconfig down/up doesn't help.

Compiled on 10.7.1 from source.

Kind regards,
shpokas
