It looks like Jan 20 21:15 (EST) judging from the CVS directory and
sounds about right as I recall.
drwxr-xr-x 2 root wheel 512 Jan 20 21:15 CVS
I included the kernel config for you, the problem is that I am
working on token-ring drivers and my code could easily be wrong.
The funny thing is, I only see the problem with high mtu's
like 4K. No problems at 1500. Also, I have an fxp interface
in the machine (in reference to the last thread).
I have also included the source to the oltr driver in-case you
want to look at the code where I allocate the mubfs... Things
appeared to start to go wrong in ReceiveFrameCompleted.
The tok (IBM) driver is compiled in but the interface was down.
