[17:33] <alkisg> Hi, I'm seeing a lot of instability with the -hwe kernel in 16.04, and I'm pondering downgrading all the schools here to 4.4 instead.
[17:33] <alkisg> Question, will I see severely degraded graphics performance, e.g. on haswell intels? I'm planning to keep the xorg-hwe stack... Or, anything else to worry about while downgrading to 4.4?
[17:34] <alkisg> (of course I reported all the bugs that I see, both to launchpad and upstream, etc etc)
[17:45] <tjaalton> no
[17:56] <alkisg> Thank you tjaalton :)
[18:09] <tjaalton> what kind of instability?
[18:14] <alkisg> Immediate reboots, https://bugzilla.kernel.org/show_bug.cgi?id=198529, vbox crashes the HOST, page faults on stress...
[18:14] <ubottu> bugzilla.kernel.org bug 198529 in x86-64 "Reboot on kernel load due to 92a0f81d" [High,New]
[18:17] <tjaalton> due to meltdown?
[18:19] <alkisg> Maybe; that one in bugzilla came right before meltdown
[18:23] <tjaalton> it's part of the meltdown fix commits
[18:26] <alkisg> It's one of the "preparation" commits, yeah
[18:27] <alkisg> Maybe it'll settle down in a few months, but having the whole school not boot is a big deal for them...
[18:27] <alkisg> And unfortunately "press shift for grub to appear, then boot with the previous kernel" isn't something that comes to everyone's mind...
