[hcflinux] More hcfpciserial segmentation faults

[Matthew Duignan]

Hi there,

I have been trying to get a HCF modem working with Mandrake 9.0.

Running the config script failed to load the driver, so I attempted to load
it manually (with insmod)

While the first two hcfpci modules loaded okay, hcfpciserial fails, causing
a segmentation fault.

The Kernel logs seem to indicate a NULL pointer dereference. This seems to
be a problem that others on this list have had - but I have been unable to
find any information on what the real cause is or how (if) it can be
solved...

The info from the kernel logs follows. I'd be more then happy to get any
extra info needed - but im away from the computer in question at the mo.

If anyone could help on this one it would be really appreciated =)

Thanks!!
Matt Duignan
