I have purchased a new MacBook Pro recently. I am facing kernel panic errors every time I use my USB data card for surfing. I have reinstalled my OS but stil get kernel panic errors.

What I need to do to resolve this issue?

add more details about the data card. Is it USB? Which make / model? Which chipset? – Sathya Jun 8 '11 at 4:51

USB data cards usually install their own kernel extensions (drivers), or require you to install those drivers yourself, so if you're getting panics while using it, it's probably your card's kernel extension that is buggy and causing the panic.

When your Mac kernel panics, it writes the panic details to a panic log file. If you paste the contents of your panic log file into your Question above, we can help you see which driver caused the panic (that information is usually, but not always, indicated in the panic log). The panic logs are written to different places in different versions of Mac OS X, so since you didn't say which version of Mac OS X you're running, I don't know for sure where to point you. But if your "new" MacBook Pro really is new, it'll be running Mac OS X v10.6.x (Snow Leopard), so the panic logs should be in /Library/Logs/DiagnosticReports .

Make sure you have the latest Mac drivers for your card. Don't trust your wireless ISP to provide the latest drivers for your card -- find who really makes the card (Novatel Wireless and Sierra Wireless are two of the biggest vendors of Mac-compatible WWAN data cards) and get the latest drivers from them. Check with your vendor to make sure the card is compatible with your version of Mac OS X. If it's a card you'd already had around, and it had been discontinued before Snow Leopard came out, it may be that they never made a Snow Leopard compatible version of the driver for that card.

You appear to have a ZTE brand USB data card. ZTE appears to be a manufacturer from mainland China. Their English-language website is at , but it sucks. By the way, they list their data cards under the "handset" category of their website. They do seem to have an English-language live tech support text chat widget on their website, so maybe you can try that. You'll probably have to have the exact model number and IMEI number of your data card ready to give to them.

Im guessing that you installed the software that was on the card itself or on a DVD that came with the card. It is very common for this software to be out of date to the point of causing issues like yours. I would grab the latest version of the software from your carrier.

Verizon: AT&T:

Both of these sites include newer "drivers" that are guaranteed to work with their connection management software. Sometimes newer kernel modules / drivers that are not included with the software can cause issues as well.

I'm not sure of the others... But they're out there

Try booting your system into 32-bit mode on the off chance that this behavior is similar to the USB tethering problem that plagues the iPhone as well.

To boot your system into 32-bit mode hold down the 3 and 2 keys when powering on your system
