For example:
disk1s1s2: ioctl(_IOR,'d',79,4) is unsupported
disk1s1 ioctl(_IOR,'d',79,4) is unsupported
disk2s1s2 ioctl(_IOR,'d',79,4) is unsupported
disk5 ioctl(_IOR,'d',79,4) is unsupported
and so on, various combinations and various disk ids.
I'm trying to work out what these persistent and unexplained errors are during some people's installations. What I believe so far (which may prove incorrect):
They seem to happen relatively often to people with Samsung drives, and cross-referencing against this thread - viewtopic.php?f=3&t=12990&start=20 - there is also a preponderence of ATI 5770 GPUs...
The '79' might be an invalid ioctl parameter since 'disk.h' on Mac OS defines up to "'d', 78" but not 79 - so this could potentially be a bug in - say - Chameleon?
EDIT:
In disk.h in the XNU source I found this:
#define DKIOCISSOLIDSTATE _IOR('d', 79, uint32_t)
So the failure is apparently happening whilst querying if the disk is an SSD or not.
Some people have reported success booting setting PCIRoot to 1.
Can anyone who has experienced this error please post here.
