Most recent kernel where this bug did not occur: 2.4.27 Distribution: Debian Sid Hardware Environment: Sun E250 Software Environment: Permedia2 FB Problem Description: I have E250 with Raptor GFX framebuffer. On 2.4.27 works fine but with any kernel which I tested > 2.6.12 frame buffer console looks very ugly and is unreadable fonts is defocusing. Steps to reproduce: Compile kernel with Permedia2 framebuffer enabled on E250
in 2.6.20 console start working, and looks nice :-)
in 2.6.24 stop working again :-(
adding pm2fb:noaccel temporary solve problem, but I cann't found way how change font and reslution mode:1024x768-8@75 or mode=1024x768-8@75 or mode:1024x768@75 or mode=1024x768@75 doesn't work
Daniel, Thanks for the updates. So this worked for you in 2.6.20? If you noticed last working kernel, maybe you could do the git bisect search for the patch that broke it (although I am not sure if this can be bisected well). CC-ing to Antonino.
Yes I can but I am not familiar wit git and bitsect. Have you any howto ? Dan
I start git-bitsect now be pantient :-)

Should be fixed in 2.6.25 by commit bc9c6a175fa8123587668c38959a105e3ccb6bbd
I must confirm 2.6.25 works fine.
