I'm not following you... but I tried adding init=/bin/bash to grub as
a kernel parameter.
I boot to console then.
I tried suspending via pm-suspend and it freezes again on resume. I'll
try again with quirks because I forgot to try it out right away.
iwl3945 is still blacklisted.

What is the point of init=/bin/bash ?
To isolate X issues? Or something else? Can you please explain a bit?

Thank you.

Valent.


I tried also:

pm-suspend --quirk-vbe-post --quirk-vbemode-restore

same issue; freezes on resume
