             Summary: Kernel panic when loading X100P module wcfxo with Intel Server Board
                 Key: DAHLIN-311
                 URL: https://issues.asterisk.org/jira/browse/DAHLIN-311
             Project: DAHDI-Linux
          Issue Type: Bug
      Security Level: None
          Components: wcfxo
    Affects Versions: 2.6.1
         Environment: Hardware:
Intel S1200BTLR
Intel Xeon 1270v2
16GB DDR3 ECC
1 X100P
1 AEX800 with 8 FXS.

Software tested:
Centos 6.3 64-bit with kernel 2.6.32-279 and kernel-ml 3.6.10 (from elrepo.org)
Ubuntu 12.10 32-bit (got the same issue).
            Reporter: Fernando Luiz Chaves Xavier Matos
            Assignee: Russ Meyerriecks
            Severity: Critical


When loading the X100P module "wcfxo" the kernel crashes.

Notes:
- On an ordinary computer (Asus M4A88T-M with Phenom II X4) everything works fine.
- Tested with another X100P and got the same problem.
- Running "modprobe wcfxo" without the X100P attached, the modules loads normally, being listed in "lsmod".

Kernel dump:
