Subject: [Bugme-new] [Bug 4217] New: radeonfb makes system hang and LCD "burn"
http://bugme.osdl.org/show_bug.cgi?id=4217
Summary: radeonfb makes system hang and LCD "burn"
Kernel Version: 2.6.11-rc3
Status: NEW
Severity: high
Owner: jsimmons@infradead.org
Submitter: marc.poulhies@epfl.ch
Distribution: debian sid
Hardware Environment:i686, Radeon Mobility M7 LW [Radeon Mobility 7500]
Software Environment:
Problem Description:
When radeonfb gets loaded, system hangs and LCD display (this is a laptop)
"burns" (seems classic when noone handles the display).
Steps to reproduce:
Starts in single user, then "modprobe radeonfb"
I tried to get some debug information by compiling the debug support, but I
can't get kernel message to another computer (I tried with netcat).
This seems to cause some problem with DRI also. I boot without radeonfb, X
starts, then a switch to console has the same effect (freeze + "burn")
(same with -rc4)

What if you load the module with option "default_dynclk=-1" ?
(Or if radeonfb is built-in, do radeonfb.default_dynclk=-1 on the kernel
command line).

Seems to work a bit more. Module loads correctly, system is still
responding, but display is not correct. System caret seems to be the
only thing displayed, and it moves when I type, but no characters get
displayed.
Do you need some more informations? (like debug output)
Thanks,
Marc

Try building radeonfb in the kernel and booting with
radeonfb.default_dynclk=-1, let me know if that works. fbdev's in
modules have always been sort-of dodgy....
The "dynclk" thing has issues, the upstream code from ATI has some bugs
plus there is something weird going on which I suspect might be a
miscompile of a bit of code in there. I'll send a patch working around
that today.
Ben.

Ok, did that. Same result. The only thing displayed is the system
caret. I can see it moving left and right while the system boots and
"displays" the messages (X is working nicely).
I did compile debug support, so I'm including the output.
Tell me if I can test something else,
Thanks very much,
Marc

Well... looks like radeonfb is actually working ... You can try booting
with radeonfb.noaccel=1 on your kernel command line and tell me what's
up ? I looks like your fbcon is having trouble actually. Not sure what's
up, I haven't had any report of that so far.
Ben.

Same result as without (screen "burns").

Well, I sent a patch that might fix the "burning" effect, if you could
get the latest bk, and try again...

I tried with rc4-bk4 (hope this is correct. I checked changelog and saw
a change on radeonfb concerning some prob with laptop), but still the
same burning effect...
