Comment 5 for bug 1641403

Same problem here: I have an Ubuntu 16.04.6 LTS VM, 32bit, running under vmware ESXi 6.5
The VM freezes randomly once a week. With kdump the machine crashes and leaves me crash dumps in /var/crash

I could try with mainline 4.4.31 kernel as suggested on the last post, but that post is almost 3 years old. Which mainline kernel would you suggest to try now or Ubuntu 16.04.6 LTS 32bit ?
