[Xen-users] continously schedule aer pcifront service

["Fan, Huaxiang" <hufan@xxxxxxxxxxxx>]

Hi gurus,

 

I used xen 4.1.0 (64bit) + dom0 kernel 2.6.32.39 (32bit) + domu kernel 2.6.32.39 (32bit) environment. I was trying to passthru Broadcom NIC to domu. The NIC can be UP but not RUNNING, on domu

#ifconfig eth0

eth0      Link encap:Ethernet  HWaddr 00:10:18:95:25:90 

          inet addr:10.0.0.3  Bcast:10.0.255.255  Mask:255.255.0.0

          UP BROADCAST MULTICAST  MTU:1500  Metric:1

          RX packets:0 errors:0 dropped:0 overruns:0 frame:0

          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0

          collisions:0 txqueuelen:1000

          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

          Interrupt:38 Memory:da000000-da012800

To debug, on domu,

#dmesg

[224.516059] Pcifront pci-0: schedual aer pcifront service

[224.516059] Pcifront pci-0: schedual aer pcifront service

[224.516059] Pcifront pci-0: schedual aer pcifront service

… …

It continuously pops up this message.

 

On dom0

It pops up these messages several times.

 

Anybody got any idea?

 

Thanks in advance!
