From my testing, it seems to work ok as long as I boot outside docking station. Can you confirm that?

Holger: When did it work? Once in a while :-) Really, I don't have an exact date, I'm testing this for about 2 years now, and sometimes it works, sometimes not.
Andreas, please post your dmesg directly after undocking. Does /dev/sr0 still exist? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Well, a bit about both.
If I accept that non-waking computer is critical, 90% of suspend problems will be of critical or higher severity... which is not useful.
So non-waking machine == normal/major ; machine that damages data during suspend == critical/blocker.
From my testing, it seems to work ok as long as I boot outside docking station. Can you confirm that?
Anyways, support for Hotplug/suspend/resume in the original IDE driver is quite broken, so it failing in such scenario is expected. The problem is that it doesn't work with libata and we seemingly still have no idea what is going on. The kernel super-strangely just checks out after a schedule() from libata. :-( Thanks. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
