           Summary: Kded4 hangs with 100% cpu usage on resume from suspend
           Product: kdelibs
           Version: 4.6
          Platform: Archlinux Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: kded
        AssignedTo: unassigned-bugs at kde.org
        ReportedBy: ricardo at devius.net


Version:           4.6 (using KDE 4.6.2) 
OS:                Linux

After resuming from suspend or hibernate the desktop freezes, although keyboard
 seems to continue working. Moving the mouse doesn't move the cursor. I am able
to switch to another terminal by using Ctrl+Alt+F2 and see that Kded4 is with
100% cpu usage. Looking at the dmesg output after resume, the only possibly
relevant errors I see are these lines:

[ 5159.368342] render error detected, EIR: 0x00000010
[ 5159.368342] page table error
[ 5159.368342]   PGTBL_ER: 0x00000003
[ 5159.368342] [drm:i915_report_and_clear_eir] *ERROR* EIR stuck: 0x00000010,
masking
[ 5159.368342] render error detected, EIR: 0x00000010
[ 5159.368342] page table error
[ 5159.368342]   PGTBL_ER: 0x00000003

Reproducible: Always

Steps to Reproduce:
1. Suspend computer
2. Resume
3. Try to do anything

Actual Results:  
Can't do anything as kwin is frozen.

Expected Results:  
KWin isn't frozen and I'm able to use my computer.

This is an Atom N270 system with i945G and all packages up to date.
