Sorry the patch seems little too large. I simply confused myself with email client's default compressor... Here's the patch again in gzip. thanks, J.I. +++++++++++++++++++++++++++++++++++ Hi Greg, Here's PCI hotplug driver patch to cpqphp driver in 2.5.45. It took a while since this patch required integration of intcphp driver and cpqphp driver, which basically nullified all previous validation/regression on intcphp, hence driver had to go thru it again... It's been verified on three servers (Itanium2(Tiger), Itanium1(Lion), and i386 Intel server) in 2.5.39 and 2.5.45 kernels.
