** Description changed: + SRU Justification/Impact: + + Per the request of the usbdux maintainer, the following patches resolve + a usbdux driver timeout and lockup. All three patches have landed in + 2.6.33 upstream. Please note that this set of patches depend on the + patch to fix bug 563436 (ie re-enable comedi drivers). I recognize we + are frozen for the upcoming release so please consider this for the + first Lucid Stable Release Update. + + TEST CASE: + + I've built a test kernel with the upstream patches applied. I've + received confirmation from the bug reporter (usbdux maintainer) that + this indeed resolves the timeout and lockup. + + ===== + This is a patch for the kernel source for Ubuntu Karmic. 2.6.31. I'm the maintainer of the usbdux.c driver. I've made a patch which resolves the issue.
