| alkisg | Hi, two schools reported completely corrupted i915 graphics when upgrading from 4.15.0-47-generic to 4.15.0-48-generic: | 14:32 |
|---|---|---|
| alkisg | I told them to try the bionic-hwe kernel (4.18) and it works. Is it a known issue, or should I collect logs/file a bug report? | 14:32 |

| alkisg | Ah, also it boots with -48 too, but only once; it breaks on reboot; then it works again with cold boot | 14:33 |
| alkisg | Xorg.0.log with -48 cold boot: http://alkisg.mysch.gr/steki/index.php?action=dlattach;topic=7771.0;attach=5037 | 14:33 |
| alkisg | And dmesg: http://alkisg.mysch.gr/steki/index.php?action=dlattach;topic=7771.0;attach=5038 | 14:34 |
| tjaalton | no idea | 14:34 |
| alkisg | Ty tjaalton; will collect more info | 14:34 |
| tjaalton | file a bug against the kernel | 14:35 |
| alkisg | Thanks | 14:35 |
| tjaalton | should be easily bisected | 14:35 |
| alkisg | Both are 32bit installations | 14:35 |
| alkisg | Will try to reproduce it with a 32bit installation locally | 14:36 |
| tjaalton | see bug 1819486 | 14:42 |
