Subject: Re: [PATCH RT] tasklet/rt: Prevent tasklets from going into infinite spin in RT

Hi Steven

Unfortunatly i am also experiencing these problems with ksoftirq running wild.

So i am also going to test this patch and see if it fixes our problem. It seems 
as if this bug is much more probable after UBIFS update and when 
"sched: RT throttling activated" hits.

Best regards
Tim
