I'm a long time GNU/Linux user, and recently upgraded to an AMD Ryzen 2700X setup (new mainboard, RAM, new everything). The system is Xubuntu 18.04.3 (64bit) and running fine, but when I resume from suspend I noticed odd instability behavior - across different applications and drives.
* thunderbird / firefox crash right after start. Infinitely until I reboot the machine.
* Virtualbox VMs with saved state fail to start with "VERR_SSM_INTEGRITY_DECOMPRESSION" error
I don't find anything suspicious in the logs, but I've never experienced thunderbird/firefox crashes of that kind in over 15 years... - and these instabilities only happen when I've resumed from suspend. Never in the first session after a clean reboot. I've ran memtest86 several times: Says memory is fine.
The data for the affected applications is stored on different physical drives - so I don't think it's a storage media I/O error. But it feels like some data is "dirty" after resume...
Does anyone else experience such a behavior?
I'm grateful for any input or suggestions!
