Thanks Vivek, I am now on the right list. Have you had any luck with the uhci-hcd driver?

Hi Bradley, You can do discussion regarding kdump on fastboot mailing list.

Basically harden the drivers to be able to initialize in a hostile environment where underlying device might be in unknown state. We have introduced a kernel command line parameter "reset_devices" and device drivers can make use of this parameter to determine that they are initializing in a potentially hostile environment and they need to first try to reset the device and then go ahead with rest of the initialization. I need to put a small patch in kexec-tools to pass this parameter to kdump kernel. Fixing individual drivers is a long painful process. Still haven't found any generic scheme to solve the problem. Thanks Vivek
