Bluescreens 6/14/2011 11:49:00 AM
It appears that the blue screens in Windows 7 usbehci.sys on my HP Pavilion Elite HPE450t are caused by a bug in the Intel 5 Series chipset used by the motherboard. Alas, no fix until HP releases a BIOS update.

Eric Intel has updated this errata to claim that this problem only happens with "one proprietary GUI application." Unless by that they mean "Windows", they're lying.
Eric Note: Someone on the USB team in Windows provided me with a script you can run in the debugger to unset the bits that enable the buggy feature. Email me for details.
