Unfortunately no...
With this patch, booting will stop during the execution of
the following lines (in ata_piix.c: piix_init_sidpr()):
if (pci_resource_start(pdev, PIIX_SIDPR_BAR) == 0 ||
pci_resource_len(pdev, PIIX_SIDPR_BAR) != PIIX_SIDPR_LEN)
return;
which might suggest this is not ata_piix related problem I'm afraid...
Again, please note if I keep the AC adapter plugged to MacBook,
there is no such problem happening. It happens only when running with battery.
