I've experienced some kernel panic after trying to compile gentoo kernel for a Sun UltraSPARC T5120 Server. The kernel panic came from a missing support for the SAS disk controller in the menu config. I've wasted so much time because I had no clue about the hardware I was using.
I know that the kernel config depends on what you plan to do with your machine but I want to have a configuration file that at least match my hardware !
Is there a website or database that provides menuconfig's kernel configuration files for known or branded hardware like Dell Server or Apple computers ?
