[hsflinux] modprobe of hsf modules brings system to its knees

we are aware of issues with newer 'module-init-tools' packages and the 
modem drivers and we are currently investigating on this problem. In the 
meantime, please try to downgrade your 'module-init-tools' package to 
one of these versions :


For the IRQ problem, please send us the output of 'dumpdiag'. Type the 
following in a root shell:

hsfconfig --dumpdiag

This command will generate the dump and you should generate this dump 
after the modem driver is no longer working.

Just send us the generated file located in /tmp ('hsfdiag.txt').
It'll help us solve the problem.
