Did deep sleep broke for anyone else recently or is it just me? (programming.dev)

I was running KDE Neon on ThinkBook 15 G2 and had deep sleep working after adding mem_sleep_default=deep to GRUB_CMDLINE. It worked for a while until it didn't. I didn't do anything other than running regulat updates. Since couple weeks back, when going to sleep, it shows BIOS Recovery progress bar or something and restarts.

I switched to Debian and the behavior is the same. S2 sleep is next to useless as it drains something like 10% battery / hour, and the lap top is warm to touch.

This talk introduces sleepgraph, a tool that might help you debug your s2ram issues.

The talk may also convince you that, for your specific hardware, s2idle might be better than s2ram:
