I have never heard of kernel logs being written to that location, what tool do you have that does that and where is that documented? > Considering I have no access to the serial port, how do I know what went > wrong? When the kernel panics, it usually can not write to the disk, so it's a bit hard to save anything :) That being said, there are ways the kernel can save the crash information, look into the "pstore" interface and see if that will work for your hardware platform (it requires hardware to store the information across boots.) good luck! greg k-h _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
