Hi Mark, After a few tests, I'm able to better report what I encounter. As I said in the other thread, I'm experiencing the bug on -current/amd64 (not on a snapshot). It's easily reproducible when watching big movies from an NFS mount point. When "watchdog timeout" appears, the box froze : I cannot even cleanly reboot. My interface is: em0 at pci2 dev 0 function 0 "Intel 82571EB" rev 0x06: apic 6 int 16 Full dmesg follows. After reverting em(4) to 09/25, as Stuart suggested, everything is OK. Your diff is also working for me : I cannot reproduce the bug after an hour of stress test.
