Subject: Re: kernel panic with latest DSS
Can you try this patch?
I haven't run into this earlier as I always have DSI compiled in. It
possibly doesn't behave correctly in that case either, but doesn't
crash.

Subject: [PATCH] OMAP: DSS2: initialize dss clk sources properly
Clk sources were not initialized, leading to kernel crash, or possibly to
strange behaviour if DSI was compiled in.

[Hiremath, Vaibhav] Tomi, No this is not helping here, one thing I am
not able to understand how does this related to reboot? The crash is
happening because the disable is getting called multiple times. So I
think the check (added by my patch) is necessary here.
Also I am seeing this crash irrespective of DSI enabled or not.
Hmm, reboot? I'm not following. I don't see any patch from you in this
mail thread.
Are you perhaps talking about some other issue?
Tomi
