My LCD monitor is out of work. I am just going to post the hotfix for it until I have got my monitor back.Quote:

with "RIFS-ES-SCHEDULER-3.5.x Hotfix For RIFS Offical Emergency" the kernel compiles without errors
but rsyslogd fails on boot (similar to https://code.google.com/p/rifs-sched...es/detail?id=2)
root@tux:/var/log# rsyslogd
Error during class init for object 'rsyslog runtime' - failing...
rsyslogd initializiation failed - global classes could not be initialized.
Did you do a "make install"?
Suggested action: run rsyslogd with -d -n options to see what exactly fails.
rsyslogd run failed with error 22 (see rsyslog.h or try http://www.rsyslog.com/e/-22 to learn what that number means)
I will start finding the reason of why rsyslogd failed(including my box, but I don't use rsyslogd at all) after few days(or even longer). In this month I am busy.Quote:

Can anyone describes about this issues? I can compile the kernel with Tickless.
I'll see if I can find some time and try compiling the kernel with ticklessQuote:

this is with genkernel failing:
genkernel has been picky in the past where it failed with genkernelQuote:

whereas with normal "make" it DID compile cleanly
might be the same this time ... compiling manually with 1 thread now ...
edit:
will start completely from scratch and see if it works ...
ok, confirmed: it fails:
