Bug#532345: dahdi-source: System freeze with no escape by sysreq or whatsoever on dahdi_cfg

[jkl345 at alice-dsl.net]

Package: dahdi-source
Version: 1:2.2.0~dfsg~rc5-1
Severity: grave
Justification: renders package unusable


I am using HFC-S PCI BRI card.


$ sudo lspci -vvvv -s 01:02.0

$ cat /etc/dahdi/system.conf 
span=1,1,0,ccs,ami
bchan=1,2
dchan=3
# hardhdlc=3

loadzone=de
defaultzone=de


When running dahdi_cfg -vvv I get proper channel map output and messages about no echo canceler is being used. The last messages are
two identical error messages I wrote down on a sheet of paper word by word:

bchan rx fifo not enough bytes to receive! (z1=0, z2=0, wanted 8 got 0, probably a buffer overrun.

After that message there is a system freeze. The system does not respond to anything but hard reset. Not even SysRq works even though it is installed.

I will have to debug this freeze with serial console or the like...

Greetings,
