The key here is that when you cat /proc/interrupts you see that interrupts have stopped incrementing on the Etherenet interface. In the past, when this has happened it was due to IRQ routing problems with the BIOS. Normal linux would work since interrupt assignments are different between normal and Xen.
If you unload and reload the LAN driver and interrupts start again then it is something other than IRQ routing.
I verified it once again. When the interface does not work no interrupts are counted. There are broadcats in my network and I tried to ping from the outside and even then no interrupts occur. Anything else to analyze? magenta:~ # cat /proc/interrupts | grep eth0 22: 2401679 0 Phys-irq eth0 magenta:~ # cat /proc/interrupts | grep eth0 22: 2401679 0 Phys-irq eth0 magenta:~ # cat /proc/interrupts | grep eth0 22: 2401679 0 Phys-irq eth0 magenta:~ # ping 192.168.11.6 PING 192.168.11.6 (192.168.11.6) 56(84) bytes of data. --- 192.168.11.6 ping statistics --- 3 packets transmitted, 0 received, 100% packet loss, time 2008ms magenta:~ # cat /proc/interrupts | grep eth0 22: 2401679 0 Phys-irq eth0 magenta:~ # cat /proc/interrupts | grep eth0 22: 2401679 0 Phys-irq eth0 magenta:~ # ifconfig eth0 down magenta:~ # cat /proc/interrupts | grep eth0 magenta:~ # ifconfig eth0 up magenta:~ # cat /proc/interrupts | grep eth0 22: 2401684 0 Phys-irq eth0 magenta:~ # cat /proc/interrupts | grep eth0 22: 2401687 0 Phys-irq eth0 magenta:~ # ping 192.168.11.6 PING 192.168.11.6 (192.168.11.6) 56(84) bytes of data. 64 bytes from 192.168.11.6: icmp_seq=1 ttl=64 time=0.396 ms 64 bytes from 192.168.11.6: icmp_seq=2 ttl=64 time=0.240 ms --- 192.168.11.6 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 999ms rtt min/avg/max/mdev = 0.240/0.318/0.396/0.078 ms magenta:~ # route add default gw 192.168.11.6 magenta:~ # cat /proc/interrupts | grep eth0 22: 2401948 0 Phys-irq eth0 -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
