System: NetBSD intrepid 1.6I NetBSD 1.6I (INTREPID.MP) #0: Mon Oct 14 22:30:35 PDT 2002 scotte@intrepid:/misc/localsrc/netbsd/netbsd_cvs_src/src/sys/arch/i386/compile/INTREPID.MP i386
Architecture: i386
Machine: i386
>Description:
	
With many concurrent Samba accesses (reads and writes) on the machine, all
network connectivity appears to stop, and the system logs:

bge0: watchdog timeout -- resetting
bge0: block failed to stop: reg 0x3400, bit 0x00000002
bge0: block failed to stop: reg 0x2400, bit 0x00000002
bge0: block failed to stop: reg 0x1800, bit 0x00000002
bge0: block failed to stop: reg 0x4800, bit 0x00000002
bge0: block failed to stop: reg 0x3c00, bit 0x00000002
bge0: block failed to stop: reg 0x4c00, bit 0x00000002

It's unclear what is causing this, however the same card appeared to work fine
in a Windows2k server, so I don't believe this is a hardware issue.

>How-To-Repeat:
	
Seems that having more than 8 concurrent, active smbd connections reading or
writing causes this to happen, although it's unclear exactly why that
would trigger this.  There are higher network loads (throughput wise) during
other activities, and this doesn't seem to occur.
>Fix:
	
None that I'm aware of.

Interface configuration is as follows:
