>Description:
Whenever I try to get a FreeBSD iso file through ftp (transfer rate is about 3 MB/s), msk would be down. Some messages from dmesg are like:
msk0: watchdog timeout
msk0: link state changed to DOWN
msk0: link state changed to UP
mskc0: Tx descriptor error
mskc0: Tx descriptor error
msk0: watchdog timeout
msk0: link state changed to DOWN
msk0: link state changed to UP

I used FreeBSD 6.2-STABLE before, since there is some related patch for msk at FreeBSD-Current (if_msk.c rev. 1.18). I upgrade to Current, but the problem seems not solved. Certainly, I tried to add hw.msk.legacy_intr="1" in /boot/loader.conf. Whether disabling  MSI or not, the problem is as before. In order to avoid shared interrupt, I've also disabled USB device in BIOS, but not help.

Could you please tell me how to solve this problem.
Thanks a lot
