Thanks for the bug report. This appears to be a crash in the 'radeon' kernel driver.

Please try a newer kernel like https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.8.3/amd64/
and if that doesn't solve the problem then also look in the 'Additional Drivers' app to see if your system supports the proprietary AMD driver instead.

Appreciate your reply and link. I have not previously installed a new kernel. Having spent a small amount of time investigating this, it appears there are some risks updating to a mainline kernel. I'm in the middle of some fairly critical deadlines at the moment and would frankly rather save my work frequently and live with reboots than have to spend time recovering my system from some bad kernel update. If you want to close this completely understand. Again appreciate your time.

NB - I did check additional drivers, it said 'no additional drivers available.'

No problem. Don't put your work at risk. We can leave this bug 'Incomplete' and it will stay that way for 60 days. Then if there are no further comments it will close automatically.

Unsure why, but this seems to have resolved itself - now suffering from far less (pretty much no) freezes. I must have updated some software that was causing the problem and a fix has been put in place. Appreciate the help on this forum, thank you.
