Hello,

I've been trying to install Gentoo on one of my alpha-computers, a DEC 3300. But I've been having problmes with the boot-procedure. I've installed the system and compiled a kernel but when I try to boot the kernel I get:

Code:
aboot>b boot/vmlinuz-2.4.21-alpha.nogz root=/dev/sdc2
aboot: loading uncompressed boot/vmlinuz-2.4.21-alpha.nogz...
aboot: segment 0, 3407452 bytes at 0xfffffc0000310000
aboot: zero-filling 291180 bytes at 0xfffffc000064fe5c
dboot: starting kernel boot/vmlinuz-2.4.21-alpga.nogz with arguments root=/dev/sdc2


Then the screen flicks black for a second and then I get thrown out to the SRM console again with the following code:

Code:
halted CPU 0

halt code = 6
double error halt
PC = 200000000
boot failure


But when I'm booting the kernel from the cd (2.4.19) The kernel boots of nice untill i get a Kernel panic:

Code:
VFS: Cannot open root device "sdc2" or 08:22
Please append a correct "root=" boot option
Kernel panic: VFS: Unable to mount root fs on 08:22


Tough problem :]

Oh, I just saw you try to load an uncompressed kernel Image. It could be your problem. Try to boot with a compressed kernel!

Did you append the right root partition as suggested by the kernel?

Yes I did, the root-system is on /dev/sdc2 as suggested in the first code-snipplet.

Finally found the reason to my problem...

I trusted the info in /proc/cpuinfo. It told me that I had a Norritake-sub-architechture. So i compiled the kernel for Norritake but it seams as if /proc/cpuinfo played a joke on me :D Anyhow. Now am I running with a kernel for generic sub-architechture and it works fine. :)
