It shouldnt be overheating, because i have custom setting on cpu heatsink fan and the ram module has a own heatsink. Plus i have fan on case which puls out the excees heat. The segfaults happend at low load, maybe it wasnt above P2 power state. Also i have made sure that the cpu doenst exceed 90°C.
Out of tree modules are from virtual box. After disabling overcommit and apparmor i didnt experience a segfault for now. The segfaults started to dissapeer it seams. I fear that this might be a bug tied to certain order of instructions. For example if i enable debug it may change order of instruction and the bug doesnt occur. Reason that i reported this bug with package linux-image-amd64 is that i didnt know about the existence of linux-mage-4.19.0-5-amd64 and i tried to prevent creating bug file for nonexisting package. Should i file another bug and put a link to this report ? št 18. 7. 2019 o 4:04 Ben Hutchings <b...@decadent.org.uk> napísal(a): > Control: tag -1 moreinfo > > On Wed, 2019-07-17 at 01:27 +0200, m.alfa...@gmail.com wrote: > > Package: linux-image-amd64 > > Version: 4.19+105 > > Severity: important > > > > Hi. > > > > Im currently running debian buster kernel and i experienced some > segfaults. > > Segfaults are random, which prevents me from pinpointing the trigger. > > First i tried disabling overcommit on memory, the behavior stoped. > > Today it started during installing updates for libreoffice.
