Description Darren Miller 2004-10-26 07:31:20 UTC

After installing Gentoo on a C3000 HP Workstation I am having difficulty with PALO. 

according to documentation the --commandline for my setup should read 

--commandline=2/boot/vmlinux HOME=/ TERM=linux root=/dev/sda2 

Where I have no seperate boot partition. However when booting the system it fails to mount the root filesystem 

VFS: Cannot open root device "sda2" or 08:02 please append a correct "root=" boot option
Kernel Panic: VFS: unable to mount root fs on 08:02

Bug or Compatability issue with HP C3000? using liveCD release 2004.2 either way I now have non-bootable system. :(

Kernel 2.4.27-pa4 being used.

According your setup I see that you've put /boot on the same partition than /. This may cause problem if your partition crosses the 2 first gigs of the hdd.

Ok now about your problem, here are some solutions :
If you installed a kernel 2.6 and have more than one hard drive, it's possible that the newer kernel detects the hard drives in another order. You may try /dev/sdb2 instead.
It's also possible that you used a filesystem which you didn't compiled the support for in the kernel. This often happend.

If your problem is not resolved, I'll need more info. You can join #gentoo-hppa on irc.freenode.net if you want faster replies :)

genkernel was used to create the kernel, where there is presently a bug with genkernel and hppa, also SOM binaries and presently not supported or working to that matter in the kernel.

Information from Guy, remove genkernel and compile the kernel by hand.

Thanks for your assistance Guy.  the system is now booted and functioning.
