Hi, I have just updated a Debian Stable system and had an apparent full-freeze (GUI frozen, IceWM non-respondent and Ctrl+Alt+FN did nothing, keyboard lights also were fixed). Using REISUB system rebooted and everything seems normal right now. Only thing I remember changing was the addition of qlipper to the IceWM startup file, nothing else. But after the update I didn't rebooted, just logged-out of session and re-logged-in, through lightdm. System has some pendent hardware issues, so, just mentioning the freeze in case someone sees something more or less obvious in the near-hang section of journalctl:
