Description of problem:

Trying to boot into kernel fails with the below output.

Bringing up eth0

Booting has failed

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.yum update
2.reboot into new kernel
Actual results:
See above. kernel does not boot.

Expected results:
kernel should properly boot

Additional info:
kernel- still boots OK.

The system in question is a plain Toshiba Satellite L40-16D with a RealTek 8149 network interface.

It is strange that the kernel suddenly does DHCP, pulling out the cable just induces some timeouts and finally the same failure results, and as there is a similar report w/o the DHCP part on bug 462201 comment 3 I think this is probably unrelated. Still since the output is weaved form the DHCP and the root fs mounting attempt I typed in the DHCP output as well.
Comment 1 Chuck Ebbert 2008-09-21 18:44:09 EDT
Is your root filesystem really on NFS? That's what it's trying to set up...
Comment 2 Axel Thimm 2008-09-21 23:21:36 EDT
No, it never was/is. Maybe the realtek driver in 2.6.26 is too eager to do nfsroots?
Comment 3 Axel Thimm 2008-10-03 02:51:23 EDT
The same happens with kernel-
Comment 4 Chuck Ebbert 2008-10-09 22:25:16 EDT
This is apparently caused by having the ltsp-client installed. Do you have that installed?

If you erase ltsp-client and rebuild the initrd for the new kernel, everything should work.

If you don't know how to rebuild the initrd, just uninstall and reinstall the new kernel.
Comment 5 Axel Thimm 2008-10-09 23:56:24 EDT

/sbin/new-kernel-pkg --package kernel --mkinitrd --depmod --install

be good enough (as outlined from rpm -q --scripts kernel-

I just noticed the /etc/kernel/*.d directories (while trying to understand how ltsp-client, which I indeed have installed, could influence the initrd). Is there some documentation on what these do? Thanks!
Comment 6 Axel Thimm 2008-10-10 07:44:14 EDT
I confirmed that removing the ltsp-client fixes this.

Is this a bug in ltsp-client (=> move component to ltsp), or is the error in front of my monitor (=> NOTABUG)?
Comment 7 John Ellson 2008-10-10 15:33:35 EDT
The ltsp-client issue has been fixed.  See BZ #462228
