User compiled kernel. WONTFIX |
From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0) Description of problem: Recompiled the kernel, modules and editted the /etc/lilo.conf file to boot with this new kernel and its components. When the machine gets to the part where it is trying to finish loading the aic7xxx module, there would be a kernel panic with a null pointer deference error. I've tried both the new and old aic driver and it gives me the same result. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Recompile the kernel along with all the modules. 2.Edit lilo.conf to boot to this new kernel and modules. 3.Reboot the machine. Actual Results: At the stage when it is trying to finish loading the aic7xxx driver, there was a null pointer derefenrence error. Expected Results: The machine should boot with the new settings without any errors.
