pci express hotplug problem

[shivprashant]

   hi,
i am writing pci express hotplug driver for mpc8315erdb(powerpc). the 
driver uses PCI hotplug subsystem not pcie port bus driver. i am able to 
do insertion and removal of pci express cards and confirm using 'lspci' 
command. driver is working with SATA and PATA memory cards with some 
minor modifications in the kernel. the problem i am facing now is when i 
try to repeatedly insert and remove the kernel is crashing, although 
non-fatal. normal insertion/removal works fine but repeated 
insertion/removal fails. pls guide me where am i wrong or what changes i 
should make to recover from pci errors.

You should post this on the linux-pci@vger.kernel.org list, along with
the errors and crashes you are seeing, and your code that you have
written so that people can help you out with it.

good luck,
