Description Alexander Boström 2008-04-28 06:14:55 EDT
(Maybe kernel is the right component, rather?)

Description of problem:
When starting an extra X server (:1), the original server (:0) crashes when one
returns to it by closing :1. Also, switching virtual console to :0 while :1 is
running crashes both servers.

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

How reproducible:

Steps to Reproduce:
1. Install F9 preview x86_64, update, reboot.
2. Log in.
3. Either use fast user switch or su and "startx -- :1"

Additional info:

Kernel oops:

IP: [<ffffffff882f463e>] :radeon:radeon_cp_init_ring_buffer+0x128/0x35d

Thanks for the bug report.  We have reviewed the information you have provided
above, and there is some additional information we require that will be helpful
in our diagnosis of this issue.

Please attach your X server config file (/etc/X11/xorg.conf) and X server log
file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file
attachments using the bugzilla file attachment link below.

Could you please also try to run without any /etc/X11/xorg.conf whatsoever and
let X11 autodetect your display and video card? Attach to this bug
/var/log/Xorg.0.log from this attempt as well, please.

We will review this issue again once you've had a chance to attach this information.

Thanks in advance.
