My apologies if this is a duplicate - couldn't find anything related from searching...

My N900 hung the other day during an update. Now, every time the screen locks (automatically or manually), it will not resume.

SSH sessions freeze and the device does not respond to input (won't even power off). I need to remove the battery and power on to unbrick it.

I've re-flashed it, but still get the same problem (want to avoid an EMMC re-flash if possible). I was running some dev-extras apps, so I'm not expecting any sympathy

Has anyone else experienced the same (or a similar) problem? Anything I can try before nuking it?
