Re: Prism2-2002-05-19 Compilation Errors (unknown fields)

I am running Linux 2.4.9-31 (RH 7.1 update kernel source package) and there are absolutely no problems compiling hostap out of the box.

Previously I was using RH7.1 standard 2.4.2-2 and this did have the original posters' problems with pci_disable_device and the struct pci_driver members save_state and enable_wake.

However 2.4.9-31 does fix these issues.

I am also pleased to report I have not had any Linux crashes/hangs with the combination of 2.4.9-31 kernel and the Prism2-2002-05-19 release (D-link 520).
