virtual console has black text

virtual console has black text

[Todd Musall]

I've been using udev (as /dev mounted on tmpfs) and hotplug for quite
some time now without any problems, but something strange started
happening after upgrading to 2.6.7 kernel yesterday.  At boot when
hotplug starts my vc is blanked or the text color is set to black.  I
can still login, but can't see any text.  Also doing a 'reset' or
'setterm -reset' doesn't correct the problem.

I did some testing and found that when /etc/hotplug/pci.rc calls udev
for my video card (Radeon 8500LE AGP) is when the screen goes black. 
This didn't happen under 2.6.6 kernel, so I'm wondering if this is a
driver issue?

I'm not sure what cold plugging the video card actually does, but as a
quick fix I added a check in pci.rc so it skips that device and
everything seems to work fine.

Vital Info:
udev 027
hotplug 2004_04_01
kernel 2.6.7

Anyone have any ideas as to what might be causing this?

Where do you see the code in pci.rc that calls udev?  I know of no such
linkage between the hotplug scripts and udev becides the main
/sbin/hotplug program.

I think it's a driver issue.

thanks,

Greg,

Sorry for the confusion.  After a little more digging I found out what's
happening.  I appears that with this new kernel /etc/hotplug/pci.agent
now decides to load radeonfb.  This module, when loaded, causes the
virtural console screen to go blank.  I've added radeonfb to
/etc/hotplug/blacklist and now all is well.

I'm an X user and don't use frame buffer so I guess this is no big
deal.  Thanks again for the help.

-Todd
