Re: seemingly random crashes, 100% cpu

Hi,

please make sure that your kernel was compiled without the 4KSTACKS 
kernel option enabled.

You should also try to use each of the following init. strings to see if 
there is a difference:

---
AT &F W1 +ER=1; +DR=1; +MS=V92,0
AT &F W1 +ER=1; +DR=1; +MS=V92,1
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
---

Hopefully one of these will be an appropriate workaround for the problem.
