Re: [Xen-users] suddenly no network, peth0: transmit timed out

[Rémi BERNIER <R.BERNIER@xxxxxxxxxxx>]

I had the same problem today. My server
doesn't respond on ssh, ping ... but i have access on console.
This is the logs of my kernel:

Thanks in advance for your answer.

On a stable server with an uptime to
3-4 months, i had suddenly no network 
but I had access to console, i have restart network, ifup eth0 but nothing
to do, link peth0 is down !! I have restart server for it works again.

On my syslog: 
Feb  2 09:07:58 xen kernel: NETDEV WATCHDOG: peth0: transmit timed
out 
Feb  2 09:07:58 xen kernel: tg3: peth0: transmit timed out, resetting
Feb  2 09:07:58 xen kernel: tg3: DEBUG: MAC_TX_STATUS[00000008] MAC_RX_STATUS[00000000]

Feb  2 09:07:58 xen kernel: tg3: tg3_stop_block timed out, ofs=1400
enable_bit=2 
Feb  2 09:07:58 xen kernel: tg3: peth0: Link is down.
Feb  2 09:07:58 xen kernel: eth0: port 1(peth0) entering disabled
state 

I have search on google, user-list but I have not found any solution
Maybe disabled acpi ?? My server is on debian lenny, xen 3.4.2 with linux-2.6.18-xen.
I have activate iommu for a tape drive on my domU win2k3

If you have met this problem I listen you !! 
Thanks in advance for your answer !!
