The realtek device did not bounce up and down like the Intel one did, and although ifconfig said the device was up and the link LED on the card showed a connection, device seemed to be utterly dead (no reply to/from ping). Then I got the same crash as with the Intel card: root@vm-server-22:~# [ 1057.824018] ------------[ cut here ]------------ [ 1057.824033] WARNING: at /build/linux-5U_ZPM/linux-3.2.57/net/sched/sch_generic.c:256 dev_watchdog+0xf2/0x151() [ 1057.824041] NETDEV WATCHDOG: eth0 (r8169): transmit queue 0 timed out [ 1057.824049] Modules linked in: r8169 mii evdev snd_pcm snd_page_alloc snd_timer snd soundcore pcspkr coretemp xen_pcifront ext3 mbcache jbd dm_mod xen_blkfront [ 1057.824089] Pid: 0, comm: swapper/0 Not tainted 3.2.0-4-amd64 #1 Debian 3.2.57-3+deb7u2 [ 1057.824098] Call Trace: [ 1057.824103] [] ? warn_slowpath_common+0x78/0x8c [ 1057.824118] [] ? warn_slowpath_fmt+0x45/0x4a [ 1057.824127] [] ? hypercall_page+0x3aa/0x1000 [ 1057.824135] [] ? netif_tx_lock+0x40/0x75 [ 1057.824143] [] ? dev_watchdog+0xf2/0x151 [ 1057.824150] [] ? run_timer_softirq+0x19a/0x261 [ 1057.824158] [] ? netif_tx_unlock+0x49/0x49 [ 1057.824167] [] ? handle_irq_event+0x40/0x52 [ 1057.824176] [] ? __do_softirq+0xb9/0x177 [ 1057.824185] [] ? __xen_evtchn_do_upcall+0x24a/0x287 [ 1057.824194] [] ? call_softirq+0x1c/0x30 [ 1057.824203] [] ? do_softirq+0x3c/0x7b [ 1057.824208] [] ? irq_exit+0x3c/0x99 [ 1057.824217] [] ? xen_evtchn_do_upcall+0x27/0x32 [ 1057.824225] [] ? xen_do_hypervisor_callback+0x1e/0x30 [ 1057.824233] [] ? hypercall_page+0x3aa/0x1000 [ 1057.824243] [] ? hypercall_page+0x3aa/0x1000 [ 1057.824252] [] ? xen_safe_halt+0xc/0x13 [ 1057.824258] [] ? default_idle+0x47/0x7f [ 1057.824265] [] ? cpu_idle+0xaf/0xf2 [ 1057.824274] [] ? start_kernel+0x3b8/0x3c3 [ 1057.824282] [] ? xen_start_kernel+0x412/0x418 [ 1057.824289] ---[ end trace eee1d2411f3779ca ]--- [ 1057.842587] r8169 0000:00:00.0: eth0: link up Oh hum, Any suggestions etc. all very gratefully received, Best regards, Jo.
