I have laptop - HP compaq 6715s with broadcom lan card (from lspci):
10:00.0 Ethernet controller: Broadcom Corporation NetLink BCM5906M Fast Ethernet PCI Express (rev 02). I am using slackware 12.2. I compiled kernel 2.6.29 from kernel.org.
When I try to copy a file trough the LAN from this laptop with a command like this:
scp test.bin 192.168.0.1:/tmp
Some MBytes are copied and the transmit stops and there is some messages in dmesg:

After that I cannot send or receive any data through the LAN. There is no ping to anywhere.
These commands fix the problem:
ip l set dev eth0 down
ip l set dev eth0 up

And when I execute scp test.bin 192.168.0.1:/tmp there is no network again.
But this laptop has no problems when receiving data. I can copy with scp from other PC connected to the same lan with 11Mbytes/s.
I have search the web to find a solution with no success.
I have tried some kernel options like "irqpoll" and "acpi=off" with no success.

I assume that 2.6.28 was OK, and that this is a regression?

I have not tried 2.6.28, but 2.6.27.9 and there is no difference. If you wish I can try 2.6.28. If you need additional information I will try to send it.

Does the problem go away if you try "pcie_aspm=off"?
