Comment 133 for bug 1746340

Hi hariprasad. nvme-core.default_ps_max_latency_us=1500 and ASPM disabling by kernel patching worked for me, at least for the main machine (my virtual machines inside this main machine still give the error after some time). I've been using the patch for almost a month without incidents. I had the problem inside a virtual machine after some days, but it didn't happen again yet (I'm using VMs but not for too much time like in the last time the problem happened).

I'm going to try to disable TRIM but it's going to take days for me to test if the VMs give any errors. Should sudo rm /etc/cron.weekly/fstrim be enough?

Have you experienced problems installing ubuntu into your SSD? My ubuntu installation gives disk error in 8/10 tries. That is, I need to reinstall ubuntu 8 times in average for the installation to end without any problems. I didn't try to install ubuntu with the kernel patch because it's a lot of work to create a live CD instalation with a patched kernel, but maybe I'll do it some day.

I also need to try virtualbox in place of virt-manager as kaihengfeng suggested. Problem is that I need to leave things open for days to notice these errors, so it's going to take time.
