 Hi,

 My MacBookPro 5,1 does not boot using -current because memory
 inside the ACPI kernel module is used after free.

 The following patch temporily mitigates the problem:

 /usr/src/sys/dev/acpica/Osd/OsdMemory.c

 void
 AcpiOsFree(void *Memory)
 {
 + if (cold == 0)
 free(Memory, M_ACPICA);
 }

 Is there any way to debug this from user-land?

FYI, this problem should be fixed in r214848.

While I am here, I'd like to give many thanks to hps for trying out 
patches, to avg for the great in-depth analysis and initial patch, to 
ACPICA developers for continuous support and invaluable comments!

Thank you, all folks!

And r214849.  I forgot to change one line. :-(
