linux-image-5.8.0-34-generic also crashes on boot. syslog attached.

I am holding back the kernel to linux-image-5.8.0-31-generic for the time being.

[Ken Cunningham (kencu)]

linux-image-5.8.0-36-generic seems fine, and all is working well again.

Not sure if something was tweaked/fixed or if it is just serendipity, but all is well now.
