If your Chromium browser hangs on startup - update kernel or load previous working kernel

Issue was with kernel 5.3.18-lp152.79.
Fixed with kernel 5.3.18-lp152.80.

I’m not sure where you are getting that kernel version information. I am seeing
vmlinuz-5.3.18-lp152.19-default
as the current kernel and
vmlinuz-5.3.18-lp152.18-default
as the previous kernel.

Yes, I know about that repo. But the kernels there don’t match what you posted, either – unless you did a lot of editing.

For most 15.2 users, the information is presumably that there may be problem with the current kernel. There will probably be a kernel update soon.
