Thanks for submitting this bug and helping to make Ubuntu better. It sounds like you are actually experiencing a bug in the kernel driver, so I will re-target this to the kernel.
The Oops shows the final straw was at driver_create_file(), but it got there through init_ipmi_si and pnp_register_driver. Clearly drivers/char/ipmi/ipmi_si_intf.c is not doing a good job with error handling in its init function. There were quite a few warnings and errors before that. The one which reads: [ 908.402376] Error: Driver 'ipmi_si' is already registered, aborting... makes me wonder whether in fact you already had the module loaded. Could you reboot the system, do an 'lsmod | grep ipmi_si' to make sure the module is not loaded, then, if it is not, 'modprobe ipmi_si'? Note that I'm not saying that, if it was already loaded, there is not a bug. Far from it. ** Changed in: openipmi (Ubuntu) Importance: Undecided => Medium ** Changed in: openipmi (Ubuntu) Status: New => Incomplete ** Package changed: openipmi (Ubuntu) => linux (Ubuntu) ** Changed in: linux (Ubuntu) Importance: Medium => High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/715294 Title: Loading ipmi_msghandler generates a kernel Oops -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
