CI1 causes kernel panic on Mac OS X Yosemite

On OS X Yosemite with Macbook Pro 2013 model when connected to Apple Thunderbolt display in which the CI 1 interface is connected the audio device works great but causes kernel panic after around 20 minutes. This makes the Mac to abruptly quit, which is as you might imagine really annoying.

I am using the latest drivers, and I also tried the one before the last version of the drivers without any luck.

Here is the log I get when starting the system up again:

YES!

I have the exact same problem. I’ve been arguing with customer service about it, but they won’t even listen to a Silicon Valley computer engineer. A piece of code in the driver is reading or writing an illegal memory address. Here are two crash dumps:

It’s the same exact bug, look at the fault addresses, we’ve both got 0xffffff802121e80a, so this is happening in the exact same place in the driver code for both of us.

Most of the poor souls experiencing this are probably unable to even figure out that their CI 1 is at fault, because these crash logs are indecipherable unless you’re a programmer, so that’s why hardly anyone is reporting it. I can also imagine it’s difficult for Steinberg to even correlate different crash reports with each other to see if they match, but this is a definite match.

This problem has now been reproduced on 2 systems. From the fault address, it should be possible for Steinberg’s engineers to find the line number the crash is occurring at.

The only major issue left is: How the heck do you reproduce the problem? It happens completely at random for me, spaced several days apart, so it’s some sort of borderline condition where the planets must align before it happens. If we are lucky, the problem will be obvious once the engineers know where to look. Like, somebody forgot to initialize a pointer or put in a check for zero or something simple like that.

Hello,

I can clearly see that the USB driver that you have installed is not the current one: jp.co.yamaha.driver.YamahaSteinbergUSBAudio 1.8.32 that USB-driver is not supported on Yosemite, have you tried the latest driver 1.0.9?

It shouldn’t happen with it.
http://download.steinberg.net/downloads_hardware/Yamaha_Steinberg_USB_Driver/Mac/1.9.0-2/YSUSB_V190-2_Mac.zip

Please make sure you uninstall the 1.8.32 driver before installing the new version.

Best regards,
GN

Hi,

I have the same issue. After examining the various kernel panic logs, I see that the latest involved kext is often jp.co.yamaha.driver.YamahaSteinbergUSBAudio.kext. The version I have in my OS X 10.10.5 system is v1.9.72 - SDK 10.6. How can I see if there is a fresher version?

EDIT: Ok, found, it’s here:
http://www.steinberg.net/index.php?id=12354&L=1

But it looks like the same version I’ve in my system.

Hi,

I’ve seen that the “YamahaSteinbergUSBAudio.kext” v1.9.7 is both in /System/Library/Extensions/ (deprecated) and in /Library/Extensions/ (recommended). Is this normal? Or is one of the two kext unnecessary and to be removed?

I have the same problem with Yamaha usb driver 3.0.5 on a MacMini M1

I have KERNAL issues on my Windows 10 PC. Very annoying. After restarting I normally get an error about VST-3 plugins and have to re start yet again.
