The kernel config file contains the following line: config kernel root on wd2 The kernel should therefore know that the root fs is on wd2 and not on wd1. >How-To-Repeat: Configure your system as follows: 2 IDE disks, primary and secondary master. 1 CDrom player, primary slave. Install FreeBSD 2.2.6 Release on the secondary master, labeled with autodefaults. My first disk contains Windows 95 (FAT 32). (Yes, I know, I should get rid of it, I will :) Install the boot manager on both disks (otherwise it is not possible to boot from the second disk). Install a customized kernel. I have used the config file at the end of this section. Reboot, et voila. Kernel panic while trying to mount root fs from wd1. >Fix: Work around: Put the following line in /boot.config: 1:wd(2,a)/kernel >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
