My motherboard is a Biostar M75NCD Pro, with USB 2.0 ports. The only usb drivers that will work with those ports are the usb-ohci and ehci-hcd modules. When I plug in a Linksys WUSB11 v2.6 wireless adapter, the system totally freezes (keyboard, mouse don't respond, doesn't respond to pings). This did not occur in Fedora Core 1. I know why it works in Fedora but not in Gentoo; some of RedHat's kernel patches fix the problem. After applying the patches to the latest gentoo-sources, plugging the device in no longer causes the system to freeze. The RedHat patches I applied are attached. It said that a few of the patches were already applied and asked me what I wanted to do, I hit enter to all the questions asked during the patch process. I'm requesting that any of those patches that are not already distributed in gentoo-sources be considered for inclusion. Reproducible: Always Steps to Reproduce: 1. Load usb-ohci and ehci-hcd modules. 2. Load 3rd party modules for device (http://at76c503a.berlios.de) 3. Plug in the device, system will freeze.
Created attachment 30449 [details, diff] RedHat patches that fixed the problem. These are the RedHat patches that fix the problem. Please consider them for inclusion in the gentoo-sources kernel.

Please do not attach binary blobs here. Can you attach the text version of the patch?
What kernel version are you having problems with here? Also, you included a module from a third party, please contact them about problems (and ask them to submit the driver for inclusion in the main kernel tree so that we can support it and you will not have to add it to the machine on your own.)
Already contacted the providers of the driver, it seems to be a rare problem, and they don't want to include the drivers in the kernel. I'll attach the patches in text format.
Created attachment 30450 [details, diff] one of the patches don't know which of these patches are already included. submitting all of them.
Created attachment 30451 [details, diff] another patch
Created attachment 30452 [details, diff] 3rd patch
Created attachment 30453 [details, diff] 4th patch
Created attachment 30454 [details, diff] 5th patch
Created attachment 30455 [details, diff] 6th patch
Created attachment 30456 [details, diff] 7th patch
Created attachment 30457 [details, diff] 8th and final patch
I added all 8 patches. Some are already included in gentoo-sources, don't know which. I reccommend including the other ones.
Comment on attachment 30450 [details, diff] one of the patches has nothing to do with this issue
None of these patches would help (they are all usb-serial, usblp, or usb-storage specific). Again, which kernel version are you using? And if the author of the driver doesn't want it included in the main kernel trees, then you are going to have to work with them, we can't help out much at all, sorry.
are you positive they wouldn't help? I'm using latest gentoo-sources. 2.4.25-r2. I'll work with the driver's author, I guess. Thanks for your help.
Yeah, I'm sure. I think I know the linux usb code pretty well :) Please work with the driver author, that's the only way to work on fixing this.
Hi! Just to let you know, I think I have a similar problem. I have tested versions 2.4.25-r1 and 2.4.25-r2 of gentoo-sources as well as vanilla-sources 2.4.26. I have tried versions 0.10 and 0.11 of the berlios driver for Atmel AT76C503A based USB WLAN adapters. My motherboard is Abit NF7-S ver. 2.0 (nForce 2). My system doesn't usually freeze when I plug in a TekComm USB WLAN adapter (fccid: IIO-0232USB611, vid: 0x1371, pid: 0x0002). Only the network "freezes" after a while (from seconds to tens of minutes). Unplugging the USB device, trying to restart (or stop) the interface or shutting down the computer after the freeze will cause a kernel panic (This msg with ver. 0.10.

It worked fine with kernel versions 2.4.25 and 2.4.26 (both downloaded directly from www.kernel.org). I will send this information also to the author of driver. But, if there is something that I could check, please, let me know what (and how :) Thanks.
Try applying the RedHat patches I attached to the kernel. I doubt it will work, bu t it's worth a try. Or you can try the latest Gentoo 2.6 kernel, I'm running that with no patches, and my internet runs fine.
