[hcflinux] Fedora 2.6.13.x kernels and hcfpci modem

Hi there,

I am using the hcfpci modem drivers on Fedore Core 4 and I also run custom 
kernels from the Fedora development branch.

I noticed from about 2.6.13-1.1542 onwards, the ASYNC_CALLOUT_ACTIVE 
definition had been removed from the kernel's header files and that the 1.06 
drivers stopped working - up to then, the 1.06 driver (with the patches 
applied) compiled correctly.

Actually, it is not so much that the driver would not compile but that there 
were 4 names that could nod be resolved at load time:


I realise that the "official" kernel is the only one that really needs to be 
supported, but I am curious to know whether these later 2.6.13 kernels are 
being tracked and whether this issue is likely to be resolved in the near 

All I have been able to gather from web blogs is that serial callout related 
code was being purged from the 2.6.x kernel... I have not been able to find 
anything more specific at this stage.

I can provide debug dumps, but as I said I realise that it is impossible for 
Linuxant to support every unofficial kernel out there so I am not expecting 
an immediate solution!
