[Freeswitch-users] Debian packages for ARM/MIPS/POWERPC

[Komar, Jason]

I get nothing in debug or sip trace. It always dies at mod_spandsp_fax so I
figured it was in that module. At that point freeswitch just restarts
without throwing any errors.

Kernel log shows:

Dec 10 14:16:17 antman kernel: [ 5949.832802] Alignment trap: not handling
instruction ecb17a01 at [<b44fe32c>]
Dec 10 14:16:17 antman kernel: [ 5949.834290] Unhandled fault: alignment
exception (0x001) at 0xb4546e4a

The only part of the exception that is the same every time it happens is
"instruction ecb17a01."

I would have just opened a JIRA, but I didn't think this was enough
information. I have been Googling trying to figure out how to get more info.
