Summary: cfag12864bfb messing up vc on load
Product: Drivers
Version: 2.5
KernelVersion: 2.6.21+
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: low
Priority: P1
Component: Console/Framebuffers
AssignedTo: jsimmons@infradead.org
ReportedBy: devzero@web.de
Latest working kernel version: n/a
Earliest failing kernel version: at least 2.6.21
Distribution: opensuse 10.3
Hardware Environment: vmware
Software Environment: opensuse 10.3 + kernel 2.6.26rc1
Problem Description:
when doing some module regression testing (load/unload most available modules),
cfag12864bfb driver always kills the local console on load and locks you out.
visible area of vc shrinks to 16x4 and output freezing. this happens if you
don`t have appropriate hardware attached, cannot test with hw attached (don`t
own such). no vc switching afterwards. cannot unload module from remote (ssh)
either. need reboot.
Steps to reproduce:
save all of your important data, switch to textconsole, modprobe cfag12864bfb
dmesg shows:
Console: switching to mono frame buffer device 16x8
fb0: cfag12864b frame buffer device
contacted the author who confirmed the issue and tells that this didn`t happen
initially. iirc, he thinks this is a regression due to change in framebuffer
layer. didn`t get a response since then, maybe he`s lacking time.
i`m putting it here so it`s being marked as a ToDo and won`t get lost.
