Public bug reported:
My system has been intermittently freezing (from once every couple of
days up to several times a day; absolutely everything appears to be
frozen, only the magic sysrq key works) for the past couple of weeks.
Nothing in particular has changed recently other than updating packages.
I've finally been able to get linux-crashdump set up so I at least have
an error message to work with. I've attached the dmesg log it collected.
I also have the kdump file it collected, which I'm hesistant to upload
as I imagine it likely contains sensitive information (and it's also
quite large), but let me know if there's any analysis it would be
helpful for me to perform with it.
