klibc recompilation -> kernel panic

Hi all,
in an attempt to get uvesafb working, I have recompiled klibc against my kernel.
But when I reboot with the new image, I get a kernel panic.

-/init: 44: replace: not found
-/init: 44: replace: not found
export: 44: bad variable name

like this one, it seems I'm not the only one with the problem.

However, my setup is a bit different from what is specified in the afore-mentioned thread:

First of all, I am on kernel-2.6zen/x86_64 with UVESAFB compiled in permanently.

Then, here are snippets of the diverse files involved:

klibc-PKGBUILD:

pkgname=klibc
pkgver=1.5.8
_klibcbranch=Testing #Stable/Testing
_kver=2.6.24-zen
pkgrel=1
pkgdesc="a minimal libc made for early-userspace"
arch=(i686 x86_64)
url="http://www.kernel.org/pub/linux/libs/klibc/"
license=('BSD')
groups=('base')
options=(!ccache)
source=(http://www.kernel.org/pub/linux/libs/klibc/$_klibcbranch/$pkgname-$pkgver.tar.gz
        multiple_raid_assembly_fix.patch
        klibc-compile-shared-by-default.patch
        klibc-module-init-tools.patch)

build()
{
  cd $startdir/src/$pkgname-$pkgver
  #INI_DEBUG causes ipconfig to fail within kinit
#  sed -i "/#define INI_DEBUG/d" usr/kinit/kinit.h
  ln -sf /usr/src/linux-${_kver} linux

#  patch -p1 -i ../multiple_raid_assembly_fix.patch || return 1
  # make klibc-module-init-tools compile
  # don't build insmod
#  patch -p1 -i ../klibc-module-init-tools.patch || return 1
  # compile binaries shared by default
  patch -p1 -i ../klibc-compile-shared-by-default.patch
  make EXTRA_KLIBCFLAGS='' || return 1
  make INSTALLROOT=$startdir/pkg install
  #simplify
  mv $startdir/pkg/usr/lib/klibc/bin/sh.shared $startdir/pkg/usr/lib/klibc/bin/sh
  rm $startdir/pkg/usr/lib/klibc/bin/mknod
  rm $startdir/pkg/usr/lib/klibc/bin/kill
}
md5sums=('22c7774f0022311fef8a4f30a1a37231'
         '8d257d50a4554d57b8f461c6a87a2877'
         'c263a7c3fd290fcc84a4e230d456d022'
         '4d78311ebce63f2fbb711f8518e71839')

(on spock' site it says to better use klibc 1.5.8 upwards, this is in testing branch, and only the last patch from abs would apply cleanly.)

/etc/mkinitcpio.conf:

# All MODULES defs are commented out...
BINARIES="/sbin/modprobe"
FILES="/etc/modprobe.conf \
        /usr/share/kbd/keymaps/i386/qwertz/de-latin1-nodeadkeys.map.gz \
        /usr/share/kbd/unimaps/8859-15.a0-ff.uni \
        /usr/share/kbd/consolefonts/lat0-16.psfu.gz"
HOOKS="base udev autodetect pata uvesafb keymap v86d userui uresume filesystems"

(v86d is provided b AUR/v86d which I have installed)
I suppose that the uvesafb hooks both aren't really needed when uvesafb is compiled in, but it shouldn't cause a kernel panic to leave'em there, should it? (It's somehow a leftover of the wiki, which describes how to set it up with a uvesafb module.)

Any hints on what the problem could be?
TIA

Re: klibc recompilation -> kernel panic

The kernel panic has nothing to do with uvesafb and the hooks, it is a problem between klibc and 2.6.24 kernels. If (as in some configurations) you can not use uvesafb without a recompiled klibc against 2.6.24, I think you have to wait until a fixed klibc is out. Till that moment, do not recompile klibc and (as a consequence) do not use uvesafb.

Re: klibc recompilation -> kernel panic

I will update the wiki article to alert about this risk

Just to make sure I understand it right: You're saying that even klibc 1.5.8 (from testing branch) probably/possibly hasn't fixed the issues yet (and thus 1.5.8 wouldn't fall in the "fixed klibc" category)?

Thanks for your help so far,
Andreas

Re: klibc recompilation -> kernel panic

Ugh, using something that is "in testing" to boot your system is never a good idea. That said, you MUST get the abs patches to apply if you want to do this. You're going to need both klibc-module-init-tools and klibc-extras.

Additionally, show me your kernel command line. You have a lone "44" in there somewhere which is breaking the mkinitcpio hooks.

ah. good to know. I'll see where they fail when I get to it. (I used that version because spock suggested "1.5.8 or newer" on his site. It's from December 11th, so I was hoping it'd be okay even tho still in testing branch. Well, that's what I have the testing boot image for...)

Additionally, show me your kernel command line. You have a lone "44" in there somewhere which is breaking the mkinitcpio hooks.

You mean /boot/grub/menu.lst:

...
# (2) Arch Zen Test
title  Zen Test
root   (hd0,2)
kernel /vmlinuz26zen showopts root=/dev/sda6 resume=/dev/sda8 video=uvesafb:1024x768-32 ro
initrd /kernel26zen-test.img
...

Also, in messages.log, it says:

 Kernel command line: root=/dev/sda6 resume=/dev/sda8 video=uvesafb:1024x768-32 ro

I'm in non-testing mode now and will try to investigate further (get the exact error message and search for any 44's) when I find the time.

Re: klibc recompilation -> kernel panic

The problem for my opinion is in kernel 2.6.24, because if i compile klibc on kernel 2.6.24, recreated the mkinitcpio, and if i run on kernel 2.6.22 or 2.6.23, the kernel works fine, but only on 2.6.24 go in panic, with this error:

::Loading Initramfs
-/init: 44: replace: not found
-/init: 44: replace: not found
export: 44: bad variable name

.

I have tried with klibc 1.5-3 and with klibc 1.5.8.

Developer/TU: Can you resolve this bug ??

Re: klibc recompilation -> kernel panic

You're missing klibc-extras. I said that.

Re: klibc recompilation -> kernel panic

klibc-extras doesn't compiles on kernel 2.6.24, this is the log of makepkg for klibc-extras: http://pastebin.archlinux.org/28770 .
I have already write on bugs.archlinux: http://bugs.archlinux.org/task/9482

Re: klibc recompilation -> kernel panic

I had the same problem with klibc-1.5-4 (which seems to be retracted) I had to upgrade to testing klibc-1.5-5 to solve it
