How to force Ubuntu/Debian/Mint to unload modules at suspend-to-disk?

Question

I put a DVB-T card into the computer, and now the system hangs at suspend to disk. CTRL-ALT-DEL does not work, hard reset is necessary.

I have a faint memory of the trick being to remove the modules at suspend and reload at resume. I can neither google nor remember how to do it.

Any hints, links and the like are appreciated.

PS I've tried rmmod dvb_bt8xx, but the system hung anyway - will the system suspend at all?

Answer 1

I had issues with this before with wireless drivers, I think that I edited my /etc/pm/config.d/modules with the following:

SUSPEND_MODULES="dvb_bt8xx othermodulehere"

Hopefully I recall that correctly - that is assuming you use pm-utils.
