Hello all.
Running Proxmox 4.3 on my FX-6300 system with 8GB of RAM just to try some things out. Aftert about day of just letting the system idle (no running VMs or anything), I notice that the server has a red X in the web interface. I SSH'd in and checked the syslog to find this snippet:
The important bits that stood out to me were the two segfaults at the beginning.
Previously I was having issues with just booting Linux completely due to something with the IOMMU, so I had to boot the kernel with iommu=soft after some googling (otherwise the NIC nor any of the USB ports wouldn't work).
I've let a Memtest86+ run for about 8 hours and had no errors. SSD that Proxmox boots from is good, the PSU is healthy, and the CPU works in other systems I've tried, plus the system runs Windows 7 and 10 without any issues, so I'm a bit lost right now. Google gives me either results that are too vague or nothing at all after googling about some of the segfault messages.
I'm not sure what other debug info I should include here but if any more info is needed I'd be happy to provide it.
