System reboots after going into sleep mode, VMWare as culprit

System specs:

i5-6300U

8 GB DDR4 SODIMM, 2133 Mhz

256 GB SK Hynix SC308 NVME

Intel HD 520

Ubuntu 20.04.2 "Focal Fossa"

 

My system was having a weird issue where every time I closed the lid or told Linux to suspend the system, it would reboot if you tried to wake it up. Without warning.

 

So I tried a few basic steps.

- Reboot? No.

- Update Linux? Worked temporarily, but only short term.

 

I have a few programs with kernel modules on my system, so that was my next thought. VMWare was the one I used most and the only one I used recently, so I uninstalled that first. The issue seems fixed. I assume it was messing up with the kernel modules, given it was installed with a .bundle downloaded from the VMWare site and not through a repository, therefore had no way of updating the modules with the rest of the system on its own.

The reason this is being posted, is a question as to maybe how to get around this or to update it manually if this was the problem. This is only an assumption.

Sleep and wake up issues are most likely due to hardware/drivers, software will make no roll IMO.

 

Any how the fact uninstalling VMWare fixed your issue, doesn't mean it is caused by VMWare, it could be that VMWare is triggering a hardware (most likely the CPU) and causes the failure.

 

I would recommend updating your BIOS and ME firmware in case you have Intel chip if they are not up to date, and try install the latest drivers.

 

I have no issues at all in my Windows host, but when it comes to the guests, windows or Linux, none of them can sleep, and I always disable sleep in all my guests upon install.
