Hi all,
I am testing out a modem driver module that works fine on 2.2.14 and
2.2.16. On 2.4.0-test9 I can insmod it with no problem.
When I open up minicom to test out some AT commands I get the kernel oops
below right away, and the system hangs.
System info:
Kernel 2.4.0-test9, gcc version egcs-2.91.66 19990314
Pentium III 450, 128 MB RAM
2 IDE Hard drives
Modem is a 56K speakerphone
I rebooted and loaded the module again, then ran ksymoops. I am assuming the
errors and warnings have something to do with the fact that I had to reboot,
but the code looks fine out of ksymoops. If any other info is needed please
ask.
Here it is:
