Before I had a chance to try uninstalling the nvidia driver, the laptop crashed again, and then I was unable to get it to boot across multiple (10+) attempts. After catching kernel output on one hung boot (by pressing Esc to clear plymouth), I was able to see that the hardware hang happened right after the start of gpu-manager.service. So I went into the firmware and tried disabling hybrid graphics in favor of discrete graphics.
The machine booted successfully on the very next boot and has been stable now for just over a day (at the expense of having no brightness control). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1939349 Title: frequent hangs with latest hirsute kernel (nvidia graphics) Status in linux package in Ubuntu: Confirmed Bug description: After upgrading to the latest kernel, I am experiencing frequent kernel hangs. The system does not respond to Alt+SysRq, and I have to power it off. In some cases the hang happens before X has even been launched at boot. When it hangs, the fan spins up to full speed.
