Re: Suspend / Resume on a Dell D420 doesnt work

Dear Patrick:

This is a widely reported problem--there are plenty of reports in
http://bugzilla.redhat.com about it.  I think it is a flaw in the
kernel, most likely, and fiddling with modules and quirks will
probably not fix it.  I posted an explanation yesterday in this list
in an email called "Resume on a Suspended Lap-top".   I just also
posted a more technical question in the fedora-devel list.  I think
the problem will trace back to particular details of the motherboard,
your BIOS, and something called hpet (high precision event timer).

Hi,

i have played around now for hours with suspend resume on my Dell D420

I have also tried s2ram from opensuse which works fine with FC6.

But now with F7 i can get suspend/resume working anymore.

i have already looked at http://people.freedesktop.org/~hughsient/quirk <http://people.freedesktop.org/%7Ehughsient/quirk>

enabling pm_trace outputs:

cat dmesg.txt | grep "hash matches"
  hash matches drivers/base/power/resume.c:70

what does this mean.
iwl3945 mac80211 are already in unload_modules.

i have removed
<merge key="power_management.quirk.vbestate_restore" type="bool">true</merge>
from the fdi file because i use the intel video driver.


now it look like this

<match key="system.hardware.product" contains="D420">
<merge key="power_management.quirk.vbe_post" type="bool">true</merge>
</match>

i have restarted the hal service but lshal | grep quirk
always outputs:
 lshal | grep quirk
  power_management.quirk.vbe_post = true  (bool)
  power_management.quirk.vbestate_restore = true  (bool)


also after a system reboot. any ideas?


has anyone a d420 with f7 and a working suspend/resume setup?

regards,
 patrick
