Same here with one of our new Dell PE6650:

Aug  3 17:25:41 pinserv7 kernel: bge0: watchdog timeout -- resetting
Aug  3 17:41:51 pinserv7 kernel: bge0: watchdog timeout -- resetting
Aug  3 18:01:16 pinserv7 kernel: bge0: watchdog timeout -- resetting
Aug  3 18:10:51 pinserv7 last message repeated 3 times

I've rsynced some tons of data via ssh to that box without any problems,
or lack of bandwidth. The card resetted while access a phpinfo() page on
the webserver: the page itself transferred, the referenced <img> (zend
logo) didn't. Simpultanously my ssh-session stalled for about 90sec and
a parallel ping stopped. 
Repeatable!
 
Parallel? Race condition?

I rebooted the machine and everything seems fine now. I'll watch this.

FreeBSD 5.4-RELEASE-p6 i386

bge0@pci8:1:0:  class=0x020000 card=0x01091028 chip=0x164414e4 rev=0x14 hdr=0x00
    vendor   = 'Broadcom Corporation'
    device   = 'BCM5700 NetXtreme Gigabit Ethernet Controller'
    class    = network
    subclass = ethernet
bge1@pci8:2:0:  class=0x020000 card=0x01091028 chip=0x164414e4 rev=0x14 hdr=0x00
    vendor   = 'Broadcom Corporation'
    device   = 'BCM5700 NetXtreme Gigabit Ethernet Controller'
    class    = network
    subclass = ethernet

The PE6650 has 4 Xeons with HTT -> 8 logical CPUs. Maybe some kind of
locking / race conditions? The kernel is GENERIC plus SMP.

See http://rabe.uugrn.org/FreeBSD/bugs/5.x/pinserv7/dmesg.boot for details

Any ideas?
Anyone with similar problems?
