[etherlab-users] Etherlab ec_master : Kernel Errors

[Olaf Holowenko]

Hi,

>> BUG: unable to handle kernel NULL pointer dereference
This may be caused by a stack overflow in YOUR program. Do you use arrays of
variable length (http://gcc.gnu.org/onlinedocs/gcc/Variable-Length.html)? If
yes - stop it!

Dear etherlab people


We have done an application using the last versione 1.5. development

We have got it working but some kernel crasch has been reported....


Attacched are the extracted of errors from the kernels

1 file of messages from the  Kernels :


-Using Canbus Over Ethercat freezes the computer making an intensive
usage...

-Or an error in kernel in the ec_master create a condition where only
hardware poweroff

can be done to unlock


- 1 file another type of error...
   Demostrate that realtime kernel cannot be used with etherlab




base on Ubuntu 12.04 64 bits kernel 3.2.0-ubuntu releases.....



Someone may help for this ?
