iowait using all my CPU after suspend

[William Murray]

My laptop suspends/resumes using fglrx. Good.
   But on resume it is often incredibly unresponsive.

The 'system monitor' applet shows CPU 100% busy, nearly all in 'IO
wait' 
  mpstat claims iowait is 7%, idle 59%.

I don't know what I am doing, but I google-guess:
 ps -eo pid,tid,class,rtprio,ni,pri,psr,pcpu,stat,wchan:14,comm | grep D

PID   TID CLS RTPRIO  NI PRI PSR %CPU STAT WCHAN          COMMAND
  238   238 TS       -   0  19   0  0.0 D    congestion_wai pdflush
  239   239 TS       -  -5  24   0  0.0 D<   get_request_wa kswapd0
  497   497 TS       -  -5  24   0  0.0 D<   get_request_wa kjournald
  760   760 TS       -   0  19   0  0.0 D+   sync_buffer    bash
  761   761 TS       -   0  19   0  0.0 D    sync_page      sh
 2641  2641 TS       -   0  19   0  5.0 Ds+  sync_page      X
 3286  3286 TS       -   7  12   0  0.1 DNl  sync_page      beagled
 3376  3376 TS       -   0  19   0  0.0 Dl   sync_page
pam-panel-icon
 4450  4450 TS       -   0  19   0  6.5 Dl   sync_page      firefox-bin

Anyone know how I should proceed?

Thank you,
                        Bill

Hm.. I learnt something. If I suspend with a click on the battery icon
it resumes. But if I close the lid it doesn't. What is the difference?

Check your power management preferences.  Perhaps your computer
hibernates better than it suspends, or vice versa.  They're different
things.
