Not sure if anyone else has experienced this. I have had Proxmox running on a N5 Pro NAS for a few months. A few weeks ago I had a kernel panic (uptime was over a month). No kernel updates or other config changes on the Proxmox.
So I connected my new GL-RM1PE to start debugging and try to catch the kernel logs. I did no changes to the default EDID. Everything worked fine for a couple of days when another kernel panic happened. This has continued, every 1 to 2 days. I managed to catch the kernel log and tried multiple action to migigate the crash but nohing worked.
In my analysis of what had changed to start this behaviour I concluded that the only real difference was the newly connected GL-RM1PE. So 3 days ago I disconnected it and it’s been running fine since.
Have anyone else experienced a KVM to cause kernel panics? It was connected to the NAS via usbc/hdmi.
So you connected GL-RM1PE to debug the kernel panic and capture logs, but then new kernel panics started appearing. Have you solved the previous kernel panic?
GL-RM1PE emulates USB keyboard/mouse and captures video output from the system, but if Virtual Media is enabled, it also presents a USB storage device. This could potentially cause kernel issues. Can you try disabling Virtual Media when connecting to Proxmox?
Additionally, could you send me the logs from your Proxmox or GL-RM1PE?
I have not activated Virtual Media. I have attached the first kernel panic that happened (with KVM connected). So it might be different from the one happened after a moth of runtime without the KVM connected.
It did not log anything to dmesg before panicing. So I don’t know really. The panic above was catured using netconsole to another machine while KVM was attached.
Thank you for providing the NAS logs. After analysis, it appears the kernel panic is caused by the ZFS drive. The KVM is not the root cause, but it may have accelerated the panic. Your system would likely experience the kernel panic even without the KVM. Could you please provide additional key logs for further investigation?
KVM will read USB and HDMI signals, which increases system load and, to some extent, accelerates your system crash. But it's definitely not a critical issue.
