I've been unable to get APM suspend/resume to work with 5.3-R on my 
Thinkpad 770Z.  As released, 'apm -z' causes a lockup (it worked fine in 
4.x).  Revision 1.233 of ata-all.c fixes that, and 'apm -z' now causes 
the system to properly suspend to disk, as it had before.  However, when 
the system resumes, it spits out three errors regarding pir0, then 
panics.  This happens with or without your patch applied to ata-all.c.

Any suggestions?
Any other info I can provide that might be helpful?

Thanks,
Dave
