[08:39] <alkisg> In bionic with hwe and fully updated, is this supposed to boot? It only works with nomodeset:
[08:39] <alkisg> 38:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Raven Ridge [Radeon Vega Series / Radeon Vega Mobile Series] [1002:15dd] (rev c6)
[08:42] <tjaalton> should
[08:42] <tjaalton> I think
[08:43] <alkisg> I think it might be too new?
[08:46] <tjaalton> shouldn't be with hwe
[08:46] <tjaalton> test disco?
[08:48] <alkisg> Thank you tjaalton; it's remote, I can test e.g. a kernel from mainline ppa but not disco, could that make a difference?
[08:49] <alkisg> (or newer packages from a ppa etc etc)
[08:50] <tjaalton> what happens without nomodeset?
[08:50] <alkisg> The teacher reports a black screen right after grub
[08:50] <alkisg> So the way around it was recovery => continue
[08:50] <tjaalton> ok, test newer kernel then
[08:50] <alkisg> Thank you
[09:06] <alkisg> As far as I can tell, the hwe 5.0 failed, while mainline 5.3 worked
[09:08] <alkisg> Whoops spoke too soon, it gets console/net but no graphics
[09:08] <alkisg> [  605.074987] INFO: task gpu-manager:713 blocked for more than 120 seconds.
[09:09] <alkisg> dmesg => https://termbin.com/yl7x
[09:09] <alkisg> OK, back to nomodeset for now, if I get it locally I'll test with disco
[09:41] <tjaalton> quality
[09:44] <tjaalton> no mention of amdgpu on dmesg?
[09:58] <alkisg> tjaalton: sure, see the termbin above, lots of amdgpu errors in dmesg
[10:00] <tjaalton> ah right.. maybe #radeon would want to know
[10:00] <alkisg> Thank you tjaalton
[10:01] <tjaalton> could be old firmware causing it
[10:07] <tjaalton> maybe try installing linux-firmware from eoan
[14:45] <alkisg> Ah thanks, will try it on Friday when the teacher contacts me again
