[hsflinux] Systems crashes completely

everything seems fine in the dump you have provided and your kernel 
isn't configured in a way which is know to be problematic with the HSF 
modem driver.

It is possible that you have hit a bug in the modulation code used by 
the connection and simply using another modulation might solve the 
problem. Please try with each of the following init. strings to see if 
there is a difference:

AT &F W1 +ER=1; +DR=1; +MS=V90,0
AT &F W1 +ER=1; +DR=1; +MS=V90,1
AT &F W1 +ER=1; +DR=1; +MS=V34,0
AT &F W1 +ER=1; +DR=1; +MS=V34,1
AT &F W1 +ER=1; +DR=1; +MS=V32B,0
AT &F W1 +ER=1; +DR=1; +MS=V32B,1
AT &F W1 +ER=1; +DR=1; +MS=V32,0
AT &F W1 +ER=1; +DR=1; +MS=V32,1

Each of them will select a different modulation and have a chance to 
solve the issue. It is possible that some of them will not work at all 
and it can be normal.
