Subject: Linux 2.6.3-rc4 Massive strange corruption with new radeonfb
Date: Tue, 17 Feb 2004 13:08:50 -0700 [thread overview]
Message-ID: <403274D2.4020407@networld.com> (raw)
Upon bootup, radeonfb is obviously not initializing the hardware
correctly. Massive amounts of random-looking garbage, plus a weird
effect I've never seen before, like someone pouring milk _up_ the
screen. (Yeah, it's the best I could come up with)
It's a Dell Inspiron 8600 with Mobile Radeon 9600 and 1920x1200 LCD.
Here's the relevant parts from dmesg:
radeonfb_pci_register BEGIN
radeonfb: probed SDR SGRAM 131072k videoram
radeonfb: mapped 16384k videoram
radeonfb: Found Intel x86 BIOS ROM Image

Obviously, it isn't detecting the screen size properly. I even tried
hard-coding the resolution in the detection code, to no avail.
Any suggestions?
Thanks.
Charles
