Bug#774036: Re: Bug#774036: linux-image-3.16.0-4-amd64: Untainted Kernel shows similar issue
Hi Emil,
I have only remote access to the system for the next few weeks and I feel
somewhat uncomfortable to experiment with my self-compiled kernels on the
system or changing networking configurations.
So please apologize that I may need 3-4 weeks to test that.
I assume you suggest to follow
http://kernel-handbook.alioth.debian.org/ch-common-tasks.html
to enable PM_TRACE_RTC and rebuild the kernel, correct?
Kind regards,
Rainer
