Bug 122270 – cat /proc/fb produces no results, on udev 84, kernel 2.6.15-r2

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Adam J. Bravo 2006-02-09 09:15:55 UTC]

Short system desc:

Kernel 		2.6.15-r2
GCC 		3.4.5
udev		84
baselayout	1.11.14-r3

Blade 1000	SMP, 2x900
Graphics	Elite 3D (AFB: ... type 35 DAC 10)


Problem:

	cat /proc/fb 

produces no output, which then causes the /etc/init.d/afbinit script to fail since it relies on this to figure out where to install the 
microcode.  With no output from the cat command, /usr/sbin/rc.afb dies silently but never loads the code (but leaves afbinit saying 
"[OK]").

I don't know enough about how the "cat /proc/fb" gets its info to know if this is a bug, or if its a snafu on the part of my system 
config (which it may well be).  I've worked around the problem by hardwiring the /usr/sbin/rc.afb script to work on my system, so it's 
not too much of an issue for me, but if its a new bug which is gonna start popping up in future versions of udev or something, figured 
I'd give a heads up.

Attach (don't paste) your kernel .config and reopen then.

Attached my .coonfig, hope that helps.

udev has nothing to do with this...

[Comment 5 Greg Kroah-Hartman (RETIRED) 2006-03-13 15:47:53 UTC]

marking invalid as it has nothing to do with udev.
