Possibly (and even likely). It sounds like a very severe case of the 
same thing.

I have been running a Marvell/Yukon 100mb adapter on FreeBSD RELENG_6 
(the onboard NIC on an ASUS mb) and it does sometimes reset connections 
and dmesg shows the timeout maybe 2 or 3 times a day.  The system is 
used in-house only and does not have high load (well, except for burst 
load when serving samba and NFS shared ${PORTSDIR}/distfiles, which 
overall works fine), so it is useable with the occasional but rarely 
noticeable glitch, like a connection pausing for 10-15 seconds then 

Currently running:

FreeBSD 6.1-PRERELEASE #1: Thu Feb 23 09:03:11 EST 2006
skc0: <Marvell Gigabit Ethernet> port 0xd400-0xd4ff mem 
0xfeaf8000-0xfeafbfff irq 22 at device 5.0 on pci2
skc0: Marvell Yukon Lite Gigabit Ethernet rev. A3(0x7)
sk0: <Marvell Semiconductor, Inc. Yukon> on skc0

I should mention that this is a vast improvement from a couple years ago 
under 5.0 and 5.1 it would attach the driver to the card but the 
interface was not functional at all.

Apparently the timeout problem is fixed in -CURRENT, and will be merged 
after 6.1-RELEASE. Enjoy.

Tracking -STABLE is a Good Thing, IMHO, quite aside from the security 
updates, bugs which don't even affect you right now (but may do 
sometime) get fixed, and the -STABLE tag tends to be quite appropriate.  
I only ever used -RELEASE media for the initial install. A system I run 
at home was originally installed from FreeBSD 3.0-CURRENT, also now 
running a mid-Feb 6.1-PRERELEASE, upgraded from sources many many times 
over (build world+kernel takes just under 3 days). :-)
