Unplug USB Device -> Kernel Panic (Leopard)

I'm getting extremely frustrated and I don't know what to do. I was used to this type of thing when I ran Windows ME.

I've got a PowerBook G4 (15") and an iMac G5. iMac was running Panther, PowerBook was running Tiger and I had never had a kernel panic. About a month ago we installed Leopard on both machines and now kernel panics happen all the time. I can consistently cause kernel panics on both machines, all I have to do is unplug a USB device that can't be ejected (USB mouse, USB hub, USB keyboard, and USB Wacom tablet).

I'm really surprised I can't find anything about this through quick google searches. This can happen at any time, I can have all programs closed or various programs open. Almost every single time as soon as I unplug a USB device I get a kernel panic.

I'm running the latest software update. Anybody have suggestions? If you want an actual log report, I'll unplug something when I get home and let you know what it says.

Archive and Install Leopard again on just one of the machines to see if the problem lets up (if only one of the machines is having the issue, then select that particular machine) - especially if you installed Leopard originally by selecting the "Upgrade" option.

I second what Lars said -- this isn't a Leopard problem, it's a bad install problem. I unplug such USB devices all the time (keyboards mainly, but other such "unejectable" things as well) and have no issues with this. Furthermore, I've seen the exact phenomenon you describe happen to people running earlier versions of OS X. Sorry you're having this problem.

A log report might be useful, so if you can get that, go ahead and post it.

I'm having the same problem, I thought it was my usb hub,

because it was cheap. I've had 3 kernel panics today trying to re-arrange my usb devices on my new hub.

My usb mouse stops responding all the time but it's plugged directly into the imac.


I can't be bothered to fix this right now, busy with iphone.

How did you install leopard? I did a clean install,

not an upgrade so I don't know how it could be a bad install?


Cheers,

Once again, I state, this IS a Leopard problem.

Same thing happens to me when I unplug my Nikon, after trashing the user icon, which NEVER happened under Tiger.

I am so tired of reading the "it ain't Leopard" and "I know better" attitiude.

Leopard is a bad OS to date, fraught with problems for many users.

Please spare me any further "I'm wrong" posts.

No it isn't.

As long as you continue to post BS you can't prove, I will continue to correct you. I will, however, endeavour to correct you as collegially as possible. Cheers!

When I ran Tiger, using the same peripherals the only thing different in the equation is Leopard. I still like Leopard and will continue to use it but I've had quite a few problems and I expected better from Apple.

That's a bit over the top - Leopard has its share of bugs and some (maybe not all) of SINC's problems are being caused by the new OS - there is little denying it. Your (and possibly mine) fairly problem-free experience with Leopard does not makes it a flawless OS and not all problems can be blamed on a botched install (though perhaps some can). I think a large number of problems may be resolved with the introduction of 10.5.2 and/or 10.5.3.

I agree with everything you've said there. I never said Leopard was flawless -- quite the opposite. I never said the ONLY possibility is user error, quite the opposite. I *clearly* (in the post above) indicated that I thought the root problem was a flawed install -- NO FAULT OF THE USER. If I didn't make that clear, I'm sorry.

But there is a distinct difference between a flawed install and a DEFECTIVE PRODUCT. Sinc and Archangel are (incorrectly) claiming that Leopard is DEFECTIVE. If this were true, ALL users of Leopard would experience the defect.

This is patently false and easily disproven, therefore what they are claiming is knowingly FALSE.

If they have a bad COPY of leopard, that's STILL not their fault but STILL doesn't indicated that *Leopard* is defective, it only indicates that THEIR COPY is defective.

I hope I've made myself more clear. They have my sympathy (and my suggestions!) for fixing their issues, but as long as they continue to FALSELY claim that the entire OS is defective, I will continue to correct them, because it's a lie.
