Kernel Panic with MacOS X 10.3.5 solved

[dhns]

Dear all Mac's:

I have figured out how to solve the issue with MacOS X 10.3.5 running into kernel panic when removing the Zaurus from the cradle.

The issue appears to be a new Ethernet over USB driver provided by Apple called AppleUSBCDCECM. It appears to be intended to run DSL modems connected through USB.

You have to issue the following commands in a MacOS X Terminal window:

Code: [Select]

cd /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns
sudo mv AppleUSBCDCECMControl.kext AppleUSBCDCECMControl.kextoff
sudo mv AppleUSBCDCECMData.kext AppleUSBCDCECMData.kextoff
AND REBOOT!

Then, make sure that AJZaurusUSB is installed and everything should work fine again.

In case you have a Modem using this driver... You have bad luck and must decide between the Modem and the Zaurus.

And here a description why I think it works now:

Whoa, I just noticed something. I'm using 10.3.5, and I've been creating a ROM on my Linux box today. I realized that I've been USING THE CRADLE to get the ROM image files on my Z's CF card from OS X. And NO crash. NO problems. It JUST works. Very odd.

All the system.long has in it relating to teh Zaurus being plugged in is...

No problems. I have the kext files that you listed as needing to be moved, but they just aren't an issue for me. Some difference with using a 5600 instead of a 5500 maybe?

Yes, maybe! I am not experienced with the details of the USB protocols but I assume that devices are identifying themselves. And there might be a mismatch for the 5500G with something else.

And another idea: if there are two drivers for the same device class it might depend on unknown factors which one gets access. And if it is the AJZaurusUSB first - then it should be ok.

Let's see if others report the same issue. I have filed a Bug Report at Apple.

Yes, devices do identify themselves when plugged in. I remeber a Linux tool called USBView. Unfortunatly when I install it on my Linux box it seems to think I don't have USB support in my kernel (which I do - I use a USB Wireless adapter for internet on it), or I'd get the device info for my 5600 that way.

I'm not very familiar with OS X system layout yet (more used to Linux), but do you know if OS X has an equivalent to Linux's /proc anywhere?

[qaz2]

I've renamed the two kexts, and I no longer get a panic on disconnecting, but I now get panics while idle seemingly at random.

Could this have anything to do with the Zaurus USB driver?

[ganoe]

I'm having the same problem.  Does renaming the AppleUSBCDCECMData driver work or do panics still occur after the change?  This thread discusses the 10.3.5 update and the AppleUSBCDCECMData driver is either new or updated.  There is likely some kind of incompatible interaction between it and the Zaurus driver.

Has anyone checked with Andreas (author of the Zaurus driver) about this issue?

At least fo me it worked without idle issues after renaming - but I have used my own recompiled version of AJZaurusUSB (with Xcode 1.5 on 10.3.5 so it should use the latest interfaces).

Has anyone checked with Andreas (author of the Zaurus driver) about this issue?

I have discussed shortly with Andreas and he is now aware with the problems.
I have recommended to fix what I think is a bug in the driver and it now does no longer freeze the USB connection after sleep mode of either the Powerbook or the Zaurus. Andreas had some equipment issues so I did not get a response yet.

I have also filed a bug report with Apple - but no response so far.

There is a new 0.2.7 release of the driver online that is supposed to provide a fix for the problem.
