tg3 networking issue

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I recently updated to kernel 2.6.17-1.2157_FC5 on my FC5 laptop. Not
sure if it's related but now networking stops working intermittently.
The driver used is tg3 for a Broadcom  BCM5789 nic. In /var/log/messages
I see:

NETDEV WATCHDOG: eth0: transmit timed out
tg3: eth0: transmit timed out, resetting
tg3: tg3_stop_block timed out, ofs=2c00 enable_bit=2
tg3: eth0: Link is down.
tg3: eth0: Link is up at 100 Mbps, full duplex.
tg3: eth0: Flow control is on for TX and on for RX.

Doing a $sudo /sbin/service network restart immediately solves the
problem. I only see this happen with the download of the FC5 Unity DVD
torrent. Not with small fish like surfing or getting my mail from an
imap server on the LAN. Has anyone seen something similar? Any
suggestions how I can pinpoint/fix this?
