Mac Kernel Panic

Post by tno » Sat Jun 24, 2017 6:39 pm

MacBook with OS X 10.11.
KryoFlux Host Software for Mac OS X (10.7 through 10.11) (v2.62, 2016-08-28).
When I try to calibrate a drive:
The green LED on KryoFlux board starts blinking. Then the screen turns black and after a few seconds my Mac runs into Kernel Panic. This happens both from GUI and CLI.

Just out of interest, do you have any drivers installed for other USB devices, e.g. a DVBT stick?

I had drivers for Keyspan USB Serial port and for Wacom tablet. I removed them and it did not help.

I have tried on another MacBook with macOS 10.12 (Sierra) and it behaves exactly the same.

I installed OS X 10.11.6 on a fresh formatted hard disk and installed latest JDK from Oracle and then KryoFlux. Nothing more.
Exactly the same problem as before when I try to calibrate:
Green LED on KryoFlux board starts blinking.
Screen goes black
Then Kernel Panic.

I booted the same hard disk on an iMac and it works.
It seems that the problem occurs on at least some MacBook models.
The two models I have are:
MacBook 13, early 2009 (MacBook5,2) with OS X 10.11.6 (El Capitan)
MacBook 13, mid 2010 (MacBook7,1) with macOS 10.12.4 (Sierra)

I remember that some had a specialty with their USB handling. Obviously macOS' USB driver panics. I am confident it'd be the same if you'd start KF on another machine (board externally powered; don't try unless you're sure the PSU is good and won't damage the board), load the firmware and would then plug the board, with the firmware loaded, into another Mac.

We've submitted several tickets to Apple when the USB problems cake up with 10.10 (or 10.11?) which also broke support for other devices as well, but Apple hasn't addressed this. Not going to rant, but apparently iOS is making more money for them.

Could it be issues with hardware USB host?

I have a MacBook Pro Late 2013 with OS X 10.11.6 and KryoFlux Host Software for Mac OS X (10.7 through 10.11) (v2.62, 2016-08-28) and java version "1.8.0_111"
Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)
and KF works like a charm so far.

Nearly the same setup regarding system/software, but different hardware.
A1200 + Indivision AGA + ACA1233 & Blizzard 1230IV+SCSI + easynet
A600 + Indivision ECS + ACA620 + A604n // CD32 + SX32 MK2 + Indivision AGA
A500 + ACA500 + 5 spare A500's (one with the C= key, Serial No 3358)
