ThinkPad T20/T21 with IBM TR Auto 16/4 PCMCIA adapter.
RC2 qa0401 build, fresh install
Network setup with static IP for tr0.
1) Boot system leaving tr pcmcia out of slot
2) Login root, lsmod shows ibmtr_cs not loaded
3) Insert token ring pcmcia card into slot 0
4) In /var/log/messages I see:
Apr 3 13:32:15 lilo cardmgr: initializing socket 0
Apr 3 13:32:15 lilo cardmgr: socket 0: IBM Token Ring Adapter
Apr 3 13:32:16 lilo cardmgr: executing: 'modprobe ibmtr_cs
5) Running lsmod now shows ibmtr_cs loaded.
6) Try running /sbin/ifconfig to view interfaces will hang ifconifg. Other
VTs are still accessable at this point.
7) Switch to VT3 (ctrl-alt-f3), login root, try kill -9 ifconfig. Nothing
happens. Kill the login that works but ifconfig is still running.
8) Do something drastic and eject socket 0. drastic results kernel panic.

Nothing to do but power off at this point. I omitted alot of the trap info
above to save my fingers but if you really need it ask. This is easy to
More T/R troubles with olympic and IBM PCI Token Ring adapter. (I can open a
second bug report if needed.)
Reading http://www.linuxtr.net there have been critical ibmtr, ibmtr_cs, and
olympic patches for 2.4.x kernels. Can these be applied to the Red Hat RC2
builds? Current testing of qa0401 seems to show these are not yet applied.
Downloading qa0404 now. Is it worth retesting any of the above adapters under this new build? It appears as if the kernel version has not changed any
Believed fixed in final. Please reopen if this is not the case.
Confirmed resolve in 2.4.2-2 kernel from 7.1. No testing has been done with 7.1
2.4.3 test errata kernel yet.
Possible problem with ibmtr_cs / ibmtr when using dhcp (pump). I need to narrow
it down before I report it though, could have been a network issue. Thanks for
the work, I'll open a new bug report as needed.
