asterisk users - Jul 2007 - bristuff for hfc card on Xscale 80219

Hi,

compile and load of modules works fine.

After ztcfg I can see
.
.
Changing signalling on channel 1 from Unused to Clear channel
Changing signalling on channel 2 from Unused to Clear channel
Changing signalling on channel 3 from Unused to HDLC with FCS check

and then the board is frozen.

Any ideas?

regards
Thomas

Frozen or crashed? Do you see the console of the system? 

What kernel do you use there?

What system?

What version of Zaptel and bristuff? Is the florz patch applied?

Can you load zaptel and zaphfc those modules with debug=1

Consider rebuilding the kernel with spinlock debugging and other similar
debugging aids (assuming that the system has not paniced and it is
hanged on something).


Also consider using vzaphfc instead of zaphfc.

serial console is dead.

kernel is 2.6.18-4 debian Etch.
bristuff is latest zaptel-1.2.19 and asterisk-1.2.22
I tried older bristuff before but same result.

yes, I assume the board is frozen because of to much load on the pci bus. if 
making tail of the syslog I can see tons of lines before board is frozen.
I have seen similar messages before if using two HFC cards on old PC, so I 
assume not enough horse power for cheap HFC card and bristuff.

It might also be a spinning spinlock.

Any luck with alt-sysrq commands?

Is your system compiled as BE or LE ?
bristuff will compile but will not work on BE systems without some
patches/endianess fixes as some of the buffer pointers are little endian
Also with the existing bristuff you will get invalid data due to the fact
that the cache controller of xscale can not snoop into the DMA transfer
cycles and update the cache
To avoid this you need to allocate a non cachable memory region for buffer.
In sort. Although it compiles it does not work :/
