Can you please update source and try again?  If it does not work, 
please set a new tunable "hw.pci.do_power_suspend=0" and tell me 
whether it helps or not.  FYI, hw.pci.do_power_resume does not apply 
to suspend any more.  So, if you want to restore the previous 
behaviour, you need both "hw.pci.do_power_resume=0" and 
"hw.pci.do_power_suspend=0".  However, my hunch tells me that you 
only need the latter.

Also, if possible, I'd like to see 'devinfo -rv', 'pciconf -clv', 
'acpidump -dt', and 'lspci -vvv' output.  Note lspci is available via 
ports/sysutils/pciutils.

Thanks,

Jung-uk Kim
