Something isn't right.
Hi,
I encountered my Debian frozen this morning. This is the 2nd time this
happened, the 1st one was on April 10, with very similar symptoms: The
PC was still running, but moving the mouse or typing didn't wake up my
screens and I couldn't connect to it via SSH.
After force-rebooting, I had a look at journalctl and these are the
messages before the reboot:

It seems to be an issue with the i915 driver, potentially triggered by
snd_hda_intel.

Is anyone else seeing a similar problem? What can I do to avoid this? Do
we need anything else to narrow it down further?
Thanks for your time!
