Re: CPU slows to a crawl after resume from suspend

Here's another data point in the defects space.

Hardware: Toshiba Satellite 300CDS laptop

Software: Linux kernel 2.2.14 and apmd 3.0final (both from redhat 6.2)

Description: No problems running redhat 5.1 (Linux
kernel 2.0.34 and apmd 2.4) for 2 years. But after
upgrading to rh6.2  'resume' failures began imediately. 
On 'resume' system either locks completely, or initially 
responds to keyboard and mouse (but there's no disk activity)
and then immediately locks completely.

Workaround: Rebuilding kernel with different values for
APM config parameters failed to solve problem. Finally
found this discussion. Since the 'crawling CPU' problem
sounded similar to mine (and I was getting desperately
frustrated), I tried disabling PCMCIA services as the
original poster, Adam Spiers, suggested (very
misterioso, thelonious...). Setting 'PCMCIA=no' in
PCMCIA configuration file (/etc/sysconfig/pcmcia in
redhat) didn't fix the problem. But hiding (renaming)
the pcmcia rc startup file did. Mr. Spiers wrote that
the problem persisted, even if the the pcmcia modules
were removed before 'suspend'. But, in this case,
stopping the pcmcia service (via the rc script) allowed
'suspend' and 'resume' sucessfully.

Thanks for the tip. Hope this helps someone find a fix.
