Got access to another ThinkPad to try. This one was an R61, rather than 
T61, but still has the same Intel 82566MM ethernet phy, still uses 
Access Connections, and is a very, very similar machine. Bacula works 
just fine on the R61. The big difference between this R61 and the T61's 
I can't get Bacula to work on, as far as I can tell, is that the R61 has 
XP, while the T61's have 32-bit Vista Business. Since a similar machine 
with the same ethernet hardware works on XP, and given that I have 
Bacula working well on several Vista Business PCs, about the only thing 
it could be is a buggy Intel 82566MM Vista driver.

The latest available driver is the one failing, so the only thing I know 
to try is to start disabling "features" of the 82566MM one by one and 
see if it works. I still have not been able to get my hands on one of 
the two T61's again, unfortunately. One thing I would try first is to 
disable checksum offload, since that has caused problems in the past for 
other Ethernet controllers. Then I'll try disabling (if possible) IPV6 
for the 82566MM. If you can try any of these possibilities or have found 
a solution, please let us know.

Other than that, I'm stumped as to why the T61's apparently just drop 
the connection. If I turn on heartbeat in the client and SD then the SD 
gets "packet too big" errors, which I suspect is something similar to 
bug 1061 going on. I don't know if a timeout is the issue, anyway. The 
disconnect occurs after several hundred MBs of data have already been 
transmitted.
