I've successfully installed ( no errors ) RH6.1 on my ThinkPad 765L but I'm unable to use my Token Ring card. During IPL, I see in the log... "cardmgr 375 executing: 'insmod /lib/modules/2.2.12.-20/pcmcia/ibmre_tr'" "kernel: ibmtr_cs: MapMemPage Bad Offset" From Gnome Network Configurator, I attempt to activate tr0 and see the following in /var/log/messages... "Unable to handle kernel paging request at virtual address ......." with exception related info displayed - registers, call stack. If I switch to another console and execute "ifconfig" I get the same error text.
I believe the token-ring support is fixed as of the 2.2.14 kernel that shipped with 6.2; you might try that and see if it performs better.
No response for months so closed, assumed ok
