Hello! I have Integrity BL870c i4 blade installed with debian sid, somewhat working 4.15/4.14.x kernel series... 4.16.x kernel (and more recent ones, including latest git) does not boot ... tried to bisect (but some kernel revisions does not even compile - git bisect skip). Does it make sense to try to start reporting bugs and hangs with ia64 4.x kernel series, being 5.10 is out... Or can you please suggest what to do with this machine kernel? Thanks.
