Hello list!
This is a follow up of http://linux.derkeiler.com/Mailing-Lists/Kernel/2008-08/msg08509.html
Summary: resizing a terminal emulator window results in a lot of misaligned text on the screen. SIGWINCH signal defective.
It ends with this question and I'd like to contribute some confusion:
> > 2.6.25.9: good > > 2.6.26-rc1 bad ( +/- 10% of the resizes) > > 2.6.26.2: still bad ( +/- 10% of the resizes ) > > 2.6.27-rc3: ugly bad ( > 75% of the resizes ) > > linux-next good
> Any other versions to test ?
I got this bug after kernel upgrade from 2.6.25.25 to 2.6.26.5 on my ppc notebook. That made me wonder. On my x86 desktop I don't had that bug. I tested:
ppc, notebook 2.6.25.25 ok 2.6.26.5 bug 2.6.26.4 bug
x86, desktop 2.6.26.1 ok 2.6.26.2 ok 2.6.26.3 ok 2.6.26.4 ok !
So I diffed the config of .4 and there is an eye catcher:
ppc: CONFIG_PREEMPT (=> CONFIG_LOCK_KERNEL) x86: CONFIG_PREEMPT_VOLUNTARY
So, recompiled and tested:
2.6.26.4, x86, CONFIG_PREEMPT => bug 2.6.26.5, ppc, CONFIG_PREEMPT_VOLUNTARY => ok
Hope, this information helps you hunting the bug.
greets
