I'm asking because I have had problems with Kernels before 4.5 on new HP EliteDesk 2G machines regarding the display drivers (check https://bugzilla.suse.com/show_bug.cgi?id=974884 ). These problems were solved with kernel 4.6 and I have seen that some additional problems (there were some warnings in the journal which did not cause a visible effect) have been fixed with kernel 4.7.
First, having a 4.4 kernel in 42.2 doesn't mean fixes from 4.6 or 4.7 are not present. On the contrary, there is a lot of backports from later versions.
Second, if a particular fix is missing and it's not too intrusive, it can be backported. Opening if you file a bugreport.
Yes. Please try beta1 kernel and see whether the problem is still present. Then open another bug report mentioning the old one.
I think upgrading the kernel would solve many problems for users with newer PCs or Laptops with the Haswell chipset.
...and introduce different problems for all users.
Indeed. For example, up to 4.8-rc4 (since 4.5 or so), there has been a more severe problem wrt Skylake watermarks, which may lead to a system hang with multi displays. Also, note that the issue mentioned in the bugzilla above is specific to Skylake, and even specific to DP MST, i.e. mostly only with a docking station on such laptops. DP MST on Haswell works more or less stably. thanks, Takashi -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
