[hcflinux] Fedora 2.6.13.x kernels and hcfpci modem

[Alex F]

Jonathan,

That's correct.

I have an up to date FC4 installation with the FC5 development kernel.

The kernel is built using the kernel-2.6.spec, with the only modification
being to set the FC4 flag instead of FC5.

The development branch requires a handful of updated RPMs including kudzu,
udev, ppp and some others that I can't tell you off hand, but they don't
appear to affect this issue as I have used these updated RPMs with the
current FC4 kernel (2.6.12-1.1447) in order to exclude them from the
problem.

The initial fact I noted was that around the 2.6.13-1.1542 development
kernel, the definition of ASYNC_CALLOUT_ACTIVE disappeared from the
linux/serial.h header file in the kernel's build tree.

A quick search on the net seemed to indicate that callout related code was
slowly being removed from the kernel... I have not had a chance to dig
deeper into the issue yet.

As I mentioned in my original post, I was just thinking out loud and realise
that I'm travelling down an unsupported path, but was curious about the
implications of the evolving kernel!

Regards,

alex
