system continuously boots/reboots when usb wireless keyboard is plugged in

[Luis Villa]

With latest kernel and a new adesso keyboard:
http://www.adesso.com/products_detail.asp?productid=281

my desktop box gets 1-2 seconds into the kernel's boot sequence and immediately reboots. Remove the keyboard, boot, and plug it in during boot, and everything works like a charm. No idea where to start debugging this one- pointers welcome.

May be related to bug 40933, but not sure.

Note: the original reporter indicated the bug was in package 'kernel-image-2.6'; however, that package was not published in Ubuntu.

Still occurs with 2.6.20 in current feisty. (Was originally 2.6.15, and probably before that, though I don't recall.)

Do not change the target when it's still known not to work.

[Luis Villa (luis-villa)]

Apologies. It is... uh... 'vastly unobvious' WTF you're supposed to do in malone in that situation.

[Ben Collins (ben-collins)]

Please test the upcoming 2.6.20-4 kernel. I saw a fix go in that sounded similar to your problem.

[Luis Villa (luis-villa)]

Will take a look; am not in the same city as the afflicted box and won't be until Monday, so some time next week.

[Luis Villa (luis-villa)]

Still happens with latest feisty kernel (2.6.20-4-generic).

How utterly crazy. One possibility is a watchguard reboot (maybe by the BIOS) if the IR transceiver is drawing more current on the USB than is allowed.

Do you see any message just before the reboot if you try to boot with '(recovery mode)' ?

[Luis Villa (luis-villa)]

Unfortunately, in a bit of a fit the other night, I chucked the keyboard across the room (yay wireless!), so it is sitting in some large-ish pieces ATM. I'll try to plug it in and see if I can still duplicate the problem later this week.

Any solution to this yet ? I experienced the same continuous rebooting events overnight.
I tried the same sequence as above (Remove the keyboard, boot, and plug it in during boot,),
and the unit is still down, won't recover at all.

My kernel is 2.6.17-11. ( I rebooted with 2.6.17-10 from the box as well, end up the same results)
PC is Dell/Optiplex/SX280

Any advice or suggestion on how to rescue it back is highly appreciated..

This bug has had no activity for a considerable period. This is a check to see if there is still interest in investigating this bug report.
Sounds like Luis is no longer available for testing.
Luis, I gather this was not a continuing issue with your replacement keyboard? (ie. the issue is definitely related to the keyboard specified in the original bug report).
Has anyone with this issue tested it against any later releases?

[Luis Villa (luis-villa)]

Yeah, that is correct; I can no longer duplicate with current keyboard/kernel. (I'd offer to send someone the keyboard to debug, but like I said I threw it across the room at some point. ;)

Closing.
