freebsd stable - Jul 2006 - bce0: Error mapping mbuf into TX chain!

I would periodically get this message and have the interface go  
unresponsive.  An up/down wouldn't reset it.

Updating to rev 1.4 of if_bce.c seems to fix it.  Is this suitable  
for MFC to -STABLE?

Maybe the author is busy for real life thing?
I've CCed to him and I'll MFC it if he allows me to do the MFC.

Sorry, I've been out on vacation and just got back into town.  I'll MFC
the patch within the next day or two.

I updated my RELENG_6 system to the tip and tried the same ssh 
command which you mentioned also failed on your system.  I couldn't
duplicate the problem at all.  Are you sure you are actually using 
the new code?  My system is reporting a different driver version
than yours (mine = 0.9.6, yours = 0.9.5):

bce0: <Broadcom NetXtreme II BCM5708 1000Base-T (B2), v0.9.6> mem
0xdc000000-0xddffffff irq 16 at device 0.0 on pci2
bce0: ASIC ID 0x57081020; Revision (B2); PCI-X 64-bit 133MHz
bce0: Ethernet address: 00:10:18:15:f6:96

Are you still having a problem?  Can you change the version number in
if_bce.c (bce_driver_version) and make sure the right driver is loading?
