Qube2 can't load CoLo

It's been quiet on this list for a while, eh? Here's a question for Qube
owners:
I've been trying to get Gentoo running on my Qube 2, and while
things seem to work fine with minor glitches so far, I can't get the
CoLo chainloading to work. I've netbooted the box, CoLo loads fine from
NFS, loads my kernel, I've done all the installation of the base system,
and now I'm trying to get the Qube to boot on its own. What does work is
to netboot again so the CoLo image gets pulled from NFS, and then have
CoLo load and boot my kernel from disk by hand (it runs into problems
trying to start udev but I think I can get this fixed later, with
init=/bin/bash it's fine so far). It doesn't however want to load CoLo
from the boot partition:

It is an ext2r0 partition and vmlinux.gz is the zipped colo-chain.elf.
I'm not sure about who writes what message in that console dump but it
seems to me that CoLo isn't even being loaded. Otherwise I should get a
menu on the console in case it couldn't find the kernel or something,
right?

cheers!

Even though I've not messed with my RaQ2 in ages, that is indeed an odd error
from the old cobalt ROM. What kind of hard drive do you have?, maybe some bunk
data is stored in the MBR that's throwing the bootloader off? IMHO, the old
bootloader/ROM is a flaky, hunk of garbage anyways. You can always try flashing
colo directly to the ROM chip. Just keep it on an UPS for safety, and colo
itself should be more than stable enough to handle that.

Your udev errors, what do they entail? I've been keeping an eye out for people
running 2.6.17 kernels and having problems with userland. I'm curious to know
what glibc revision you have merged. I've got a nagging suspicion we may be
about to hit into an upgrade path issue that i ran into on my Octane, but have
yet to ascertain whether it was specific to me or not.

Thanks for the encouragement---I had been too chicken to try it yet as
the manual said to make sure the chainloading version works first.
Actually I even have a flasher but I'd have to install Windows for it in
case it screwed my flash chip, so... :)
Anyway, I tried and it worked flawlessley in a matter of seconds. Kudos
to Colonel Panic! It's still dropping me to the boot menu to load the
kernel by hand but I think that has got to do with my default.colo file,
have to check it once my new kernel compile has finished.

The error message says:
| * Mounting /dev for udev ...[ oops ]
|
|
| * The "mount" command failed with error:
|
| wrong fs type, bad option, bad superblock on udev,
| missing codepage or other error
| In some cases useful info is found in syslog - try
| dmesg | tail or so
|
| * Since this is a critical task, startup cannot continue.
My glibc is 2.3.6-r4, it's all still the original 2007.0 install image
from redhatter. But I'm quite sure that's not the problem, this looks
pretty much like a problem I had on a HPPA box a while ago. I had
disabled support for hotplug devices in the kernel since it's a server
and I thought I didn't need it. Afterwards, udevd wouldn't start any
more, complaining about some missing netlink functionality, I don't
remember exactly what it was.
On the Qube I should have dumped the config from the netbooted
installation kernel but went with "make cobal_defconfig" first, which I
found later has no hotplug support either. So I'm pretty confident it
will work once I have the new kernel compiled (it's going through the
whole 2h procedure right now because I forgot to set the clock last time
8-]). I'll post my result when I have any.

cheers!

That sounds suspiciously like you forgot to enable tmpfs support in your kernel.

Indeed, that's what it was 8-] It's working just fine now, thanks!
I'm still fighting with the recent 2.6.20 as it doesn't seem to
recognize my disk, but 2.6.17 is fine as well so far. Just dm-crypt is
*very* strange:

/dev/hda5 is not mounted or anything, and the second luksDump command
came just a second after the first one. WTF?!

And BTW, HD performance leaves much to be desired---is this normal for
a 250 MHz MIPS? My 68040/40 Amiga did not much worse over its 7 MHz bus:
| ann ~ # dd if=/dev/zero bs=1M of=/dev/hda5
| dd: writing `/dev/hda5': No space left on device

| ann ~ # hdparm /dev/hda
|
| /dev/hda:
| multcount = 32 (on)
| IO_support = 1 (32-bit)
| unmaskirq = 1 (on)
| using_dma = 1 (on)
| keepsettings = 0 (off)
| readonly = 0 (off)
| readahead = 256 (on)
| geometry = 19846/16/63, sectors = 20005650, start = 0

I was planning to put a partly crypted drive from my HPPA box in there,
and I hoped at about twice the clock it would perform better...

cheers!
