At least I had kernel panics until I added this. Chuck
Re: [gentoo-user] installation / grub boot problem
I rebuilt the kernel and double checked to get these modules (raid1, raid5, device mapper) linked into kernel, all to no avail. Any ideas? --HH On Tue, Mar 10, 2009 at 5:17 PM, Neil Bothwick n...@digimed.co.uk wrote: On Tue, 10 Mar 2009 17:09:13 -0400, Heping He wrote: When I reboot, the kernel issued a panic msg: it says can't read /dev/md/3 or (hd2,0) is invalid device.
