Description scottk 1999-02-25 20:19:14 UTC
PCMCIA token ring card cause kernel oop's.  This is a big
problem with our IBM customers.

we have gotten a fix, but we do not have any way to test

The following was suggested by a tech from IBM.

>>> Another report gave me a clue about this... the ibmtr
driver can't
>>> handle memory ranges above 0xfffff so that's causing the
kernel fault.  If you use the new drivers and comment out
>>> 0xa0000000-0xa0ffffff memory range in
/etc/pcmcia/config.opts, the
>>> card should be ok.

This may or may not affect non-PCMCIA token ring adapters.

Comment 2 scottk 1999-03-10 21:05:59 UTC
I pointed a customer to this bug page.  He reported that his 16/4
PCMCIA token ring card functions with this fix.

Comment 3 David Lawrence 1999-04-08 21:34:59 UTC
Problem is some token ring adaptors will only come up properly if you
are connected to an active token network. We are considering setting
one of these up in our lab to help duplicate this and other token
related issues.
