to help us debugging the problem please do the following:
checkout current kernel source tree
in file dev/pci/ahci.c change the line
#define NO_AHCI_DEBUG
to
#define AHCI_DEBUG
build and install the kernel (don't forget to backup an old one)
in the boot prompt type:
boot> boot -d
then in ddb:
ddb{0}> w ahcidebug 0xff
ddb{0}> c
there should appear many debug lines in the dmesg, grab the whole log
of the crash an post here.
thanks.
