A Fedora 27 KDE Xorg install sometimes freezes when opening Vivaldi, which is a Chromium-based browser. I’m able to move the mouse, but nothing else, including the usual array of keyboard shortcuts help.
It doesn’t happen every time. If it does not happen, the desktop is rock solid, including high load number crunching for hours on CPU+GPU. It has been running Fedora 25-27 for a year without h/w issues. This change is recent.
On freeze, I’m still able to SSH into the machine. Dmesg says this:
[ 125.297179] NVRM: GPU at PCI:0000:09:00: GPU-1dcba5bb-3f9b-139f-03dc-de35c8a438c8 [ 125.297181] NVRM: GPU Board Serial Number: [ 125.297183] NVRM: Xid (PCI:0000:09:00): 31, Ch 00000028, engmask 00000101, intr 10000000
Sometimes, it’s able to ‘recover’ to the login screen, but the session is gone.
If it is able to recover, which takes about 5 minutes, this shows up in dmesg:
[ 752.860554] nvidia-modeset: Freed GPU:0 (GPU-1dcba5bb-3f9b-139f-03dc-de35c8a438c8) @ PCI:0000:09:00.0 [ 754.228624] resource sanity check: requesting [mem 0x000c0000-0x000fffff], which spans more than PCI Bus 0000:00 [mem 0x000c0000-0x000dffff window] [ 754.228759] caller _nv001170rm+0xe3/0x1d0 [nvidia] mapping multiple BARs [ 754.753860] nvidia-modeset: Allocated GPU:0 (GPU-1dcba5bb-3f9b-139f-03dc-de35c8a438c8) @ PCI:0000:09:00.0
If it’s not able to recover, killing Vivaldi does not help.
