Just download linux-image-2.6.38-9-generic_2.6.38-9.43~lp757242r1_amd64.deb and install it with sudo dpkg -i linux-image-2.6.38-9-generic_2.6.38-9.43~lp757242r1_amd64.deb
Keep using the slub_debug with this new kernel, boot into it and do the same test, then please attach the dmesg output of it. I enabled usb and xhci-hcd debugging to try to get more information about the crash.
Please install the kernel I uploaded at http:// people. canonical. com/~herton/ lp757242/
