<pre>Hi Joonas. Regarding your <a href="show_bug.cgi?id=91585#c14">comment #14</a>, the lack of interaction does help. I
tried 3 things:
1) as suggested, from boot I waited until KDM logging screen. From there, with
no interaction I did suspend to disk / resume cycles using only the power
button (keyboard for DM crypt unlock at boot too). No lock-up in 40 cycles.
2) then I logged in KDM, until I got my KDE session. From there, I tried the
same: no interaction, suspend/resume cycles using the power button only. No
lock-up in 40 cycles too.
3) from there, I continued doing the suspend/resume cycles the way I used to
before. It has very little interactions: at the beginning I check hw
acceleration with glxinfo, kernel version, just to make sure I have the right
environment. Then open a konsole. At each cycle I do a "date ; echo N" where N
is the cycle number, just to keep track. Sometimes I clear the notifications,
and once in a while browse the web (uncommon, not correlated with the lock-up
as far as I can tell). So really limited interaction, mostly it's key up in
konsole to get the previous command, edit the number and type return. I got a
lock-up at the 8th resume this way.
So interaction does seem a part of it. If you'd like me to try something else,
let me know.</pre>
