Hi all

For the last 1 month i am trying to setup a HylaFAX server. i am having a Agere Lucent chipset modem.The output of lspci -vv is as shown below.

I am using Fedora release 13 GODDARD.

I installed the Modem driver that i got from the linmodems support page.

Now i am able to dialout and dialin with this driver but when i run faxgetty on the modem the kernel crashes saying segmentation fault. :(
the Bug report is shown below.

Is there any solution for this error. I tried with many combinations of drivers from linmodems site but the same error or the driver doesnt get compiled.

Any help will be greatly appreciated.

Thank you.
