| alkisg | Hi, so far 3 schools reported black screen+hang after upgrading from 4.15.0-47 to -48+: http://alkisg.mysch.gr/steki/index.php?action=dlattach;topic=7771.0;attach=5029;image | 08:16 |
|---|---|---|
| alkisg | But when they installed linux-generic-hwe, the problem was gone, so I'm not sure it's worth it to pinpoint the regression; | 08:16 |
| alkisg | so I'm just mentioning it in case it becomes more frequent... | 08:16 |
| tjaalton | alkisg: ancient hw? | 08:34 |

| ubottu | Launchpad bug 1819486 in linux (Ubuntu) "Crash from :i915 module with 4.15.0-46-generic using multi-display" [Undecided,Confirmed] | 08:34 |
| tjaalton | assuming it's i915 | 08:35 |
| alkisg | dimitris@HPEliteDesk:~$ lspci -nn -k | grep -A 2 VGA | 08:38 |
| alkisg | 00:02.0 VGA compatible controller [0300]: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller [8086:0412] (rev 06)Subsystem: Hewlett-Packard Company Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller [103c:18e5]Kernel driver in use: i915 | 08:38 |
| alkisg | tjaalton: that's the only info I have, from one of those schools | 08:38 |
| alkisg | They didn't have any issues up to -48 though; this issue mentions that -46 had a problem... | 08:39 |
| tjaalton | that's something else then and not related to graphics | 08:41 |
| alkisg | Thank you tjaalton; if it becomes more frequent I'll have a deeper look | 08:42 |
| tjaalton | file a bug | 08:42 |
| alkisg | I don't feel well to file bugs when it's not easy to provide feedback; if I can reproduce in the office that's easy; | 08:45 |
| alkisg | if not, I VNC to the school, but e.g. now that they had that easy workaround with -hwe, they wouldn't want the downtime involved to send a lot of debug information, as it usually means teachers can't give lessons then | 08:45 |
| alkisg | So they are only very happy to give debug info when they don't have workarounds :D | 08:45 |
