Re: [openib-general] [HELP] Encounter Kernel Panic when Add MellanoxHCA Supporting on 2.6.9 Kernel
Hmm, I can't make it happen here unfortunately... I just get the following on 2.6.12-rc5 with CONFIG_DEBUG_SPINLOCK: [ 26.001979] ib_mthca: Mellanox InfiniBand HCA driver v0.06-pre (November 8, 2004) [ 26.026622] ib_mthca: Initializing Mellanox Technologies MT23108 InfiniHost (:04:00.0) [ 27.326318] ib_mthca :04:00.0: HCA FW version 3.0.1 is old (3.3.2 is current). [ 27.351207] ib_mthca :04:00.0: If you have problems, try updating your HCA FW. but it actually seems to work (well enough that the port goes to active). - R. ___ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general

Dear Woody & Roland I downloaded the newest firmware and updated the system with it. Now it works. Kernel can be booted and module can be loaded successfully. Thanks for your great help. It is very useful to me.

Unfortunately not, I did not have CONFIG_DEBUG_SPINLOCK set and I did not save the old firmware before loading in the new firmware. Perhaps Lenber can get the traceback info before he updates his card. That would be helpful as I agree it is not desirable to panic on cards with old firmware. woody ___ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general

RE: [openib-general] [HELP] Encounter Kernel Panic when Add MellanoxHCA Supporting on 2.6.9 Kernel
I tried the patches (2.6.12-to-2.6.9, not svn backport) on an EM64T desktop (without HCA card). The kernel can be installed successfully. I still can't reboot the kernel on Xeon SMP server, even with the new patches (svn backport). The same error was encountered. Then I disabled the option CONFIG_DEBUG_SPINLOCK. The error message disappeared, but the kernel still can't be booted. Can I assume it is the problem of HCA card? Or the issue is relative with the SMP platform? So strange..
