Hi!
I want to keep you updated: The problem isn't fixed, still, so I
I'm running this simple script via cron to avoid uncontrolled kernel panic:
---snip---
#!/usr/bin/sh
# Detect RAM corruption. If detected log a message and reboot
# to prevent kernel panic
#cron jobs need a PATH
PATH=/sbin:/usr/sbin:/usr/bin:/bin
if journalctl -b -g 'Code: Bad RIP value|BUG: Bad rss-counter state mm:'
>/dev/null
then
MSG='RAM corruption detected, starting pro-active reboot'
logger -t reboot-before-panic -p local0.notice "$MSG"
shutdown -r +1 "$MSG"
fi
---
Still I suspect it might be related to snapshots being made. After a few days
of running the problems started again like this:
