[Qemu-devel] [Bug 1815889] Re: qemu-system-x86_64 crashed with signal 31 in __pthread_setaffinity_new()

[Christian Ehrhardt ]

The PPA was built against -proposed so I had to enable that to install all libs.
That done the 19.0.0~rc6-1ubuntu0.1 with the set affinity change reverted works 
quite nicely.

It would be great to get that into Ubuntu 19.04 until the involved
upstreams agreed how to proceed with it and we can then sort out what to
do in which package. Which after all might be after cutoff and in 19.10
then.

Thanks Timo, let me know if you need another verification on this at any
point to drive it into 19.04.
