Description Kai Engert (:kaie) 2007-09-19 11:30:41 EDT
Rawhide x86_64 Xen guest running on a RHEL-5 x86_64 host.

Problem: kernel-xen-2.6.21-2940.fc8 does not boot up.

I used "xm create -c rawhide" and I get a repeated stream of the same error message:
init[1]: segfault at 0000000000000028 rip 00002aaaaacd3f26 rsp 00007fff775050b0
error 4

The previous kernel-xen-2.6.21-2925.14.fc8 works fine.

The host is running kernel-xen-2.6.18-8.1.8.el5
(I confess I rebuilt the official kernel to enable ieee1394 support)

Comment 2 Kai Engert (:kaie) 2007-09-19 19:56:58 EDT
I updated the host to kernel-xen-2.6.18-8.1.10.el5, same problem
Comment 3 Eduardo Habkost 2007-10-11 10:01:09 EDT
Could you paste or attach the guest console output just before the segfaults 
stream begin?
Comment 4 Kai Engert (:kaie) 2007-10-11 11:23:06 EDT
Good news. Newer Kernel 2.6.21-2947.fc8xen no longer crashes
I'll resolve this bug because I no longer crash with the latest kernel.

But I'll attach a more detailed boot console output from the crashing kernel.

boot log

  xm -c create rawhide | tee logfile
produced some extra line feeds after filtering out all the boot menu data...

Chris Lalancette found the problem: the initrd was generated during the 
upgrade while an older ld.so was installed, but newer nash needed a more 
recent ld.so. Regenerating your initrd should solve the problem.

That also explains why 2.6.21-2947.fc8xen works. Its initrd was generated 
after the system had a working mkinitrd/nash/ld.so set.
