[hcflinux] ubuntu 4.10 (kernel 2.6) asm-68k problem and module loading problem

[Linuxant support (Jonathan)]

Hi,

we are not aware of this build issue with the 2.6.8.1-3-powerpc kernel 
of Ubuntu and this is strange that the file 'include/asm/setup.h' 
includes a file in a specific architecture directory (68k).

As you have found out, there are known crash issues with the HCF USB 
driver and the 2.6 kernels and we are going to take a look at this 
problem. Please try to generate the dump with the:

---
hcfusbconfig --dumpdiag --noprobe
---

command instead of the:

---
hcfusbconfig --dumpdiag
---

command, it will probably prevent the crash. You should send us the dump 
at support at linuxant.com, it will help us solve the problem.

In the meantime, you should make sure that your kernel was not compiled 
with the 'CONFIG_PREEMPT' option enabled. Alternatively, you could try 
with a fresh 2.6.10 kernel from http://www.kernel.org to see if there is 
a difference.
