Description Yves L'ECUYER 2006-09-09 12:25:13 UTC
Most recent kernel where this bug did not occur:
Distribution: Fedora Core 4 and RedHat EL 4
Hardware Environment: IBM Turbo 16/4 TokenRing PC Card2
Software Environment: kernel 2.6.16 from Fedora updates
Problem Description: 
Why to limitate in drivers/net/pcmcia/Kconfig the usage of ibmtr_cs to 32 bits
arch ?
In the lines:
----------
config PCMCIA_IBMTR
        tristate "IBM PCMCIA tokenring adapter support"
        depends on NET_PCMCIA && IBMTR!=y && TR && PCMCIA && !64BIT
-----------------
I removed with a the limitation "&& !64BIT"; then the module compile fine with
few warning, and loads fine with PCMCIA cardmanager service.
I noticed than the PC used in stand alone, the TokenRing initialisation abort
because the drivers says there is no Ring controller.

So I used the RHEL4 with 32 bit kernel, and the corresponding ibmtr_cs, and I
got the same message. So  the ring controller funtionality seams not implemented
in this drivers, but it's not a matter of architecture.

Conclusion:I used this drivers during more than 3 weeks now, with a cisco 2504
in the ring (who plays the ring controller role fine), and the communication
between my laptop (ASUS A6Q00K with TURION 64bits and Fedora Core 4/kernel
2.6.16-64bits )and the cisco 2504 is fine; protocole tested: ICMP,TCP,UDP,OSPF

Probably needs review by those with knowledge of TR architecture. Will cc to linux-tr@linuxtr.net

Any update on this bug please. Yves, is the new kernel still showing this problem?
Thanks.
