I'm having the same problem.

Was running FreeBSD-9 for a long time with an msk card, no problems or 
issues.  Upgraded to 10-RELEASE and now my card reliably hangs after 
passing a total of about 2M of traffic.

I'm running amd64 with 2G of RAM.

I can provide the exact card ID later if it helps.

I tried modifying msk_stat_count as suggested by Curtis (both my modifying 
MSK_TX_RING_CNT/MSK_RX_RING_CNT as he did, as well as by setting it 
directly to 1k or 2k in if_msk.c), but that didn't help.  With each of 
these changes, after a reboot, the card will reliably pass about 2Mbyte of 
traffic and then hang (tried multiple reboots and power-cycles with each 
iteration).

Has anyone else made any progress on this issue yet?

Has anyone tried just rolling back sys/dev/msk to the version from 
9-STABLE?

Thanks.
