------- Additional Comments From [EMAIL PROTECTED]  2006-11-10 19:34 -------
I've been testing the patch from <a href="#c52">comment #52</a> along with the
patches from <strike><a href="show_bug.cgi?id=5534" title="CLOSED CODE_FIX - No
thermal events until acpi -t - HP nx6125">bug 5534</a></strike> against 2.6.18.1
kernel for several weeks. Generally speaking they work fine. However there are a
few oddities worth noticing:

1) After resuming from suspend-to-ram temperature at TZ1 rises slightly under
the same system workload, when compared to a pre-suspend state. On my notebook
this can be easily observed when the system is idle. The increase in temperature
leads to a change of the TZ1 state from active[3] to active[2] for a  minute or
so until it gets cooled enough to return to the previous state. That in turn
once again causes a rise in temperature and the cycle is closed. The frequency
of oscilations is constant. Such a behaviour might suggest that the patch from
<a href="#c52">comment #52</a> or a combination of all mentioned earlier causes
additional runtime overhead after resuming from suspend-to-ram. I'm not sure
whether that was intention of the patch creator.

2) When I try to shutdown system after resume from suspend-to-ram, or try to
suspend to disk I experience strange behaviour of my LCD matrix. After issuing
shutdown command or receiving ACPI event from power button system seems to lost
control over display. Instead I can see something that I would call spontaneous
polarisation of pixels. Possibly I misinterpreted something and this is
irrelevant to the patch from <a href="#c52">comment #52</a> so I will welcome
any feedback. 

Tests were performed on HP nx6325 (Fedora Core 6).
