Summary:                    PCI Parity Error (Dell PowerEdge 1950 III) in spite
of actual TE420p firmware (hardhdlc only)
Description: 
Our Dell PowerEdge 1950 III Server crashes in PCI Parity Error after one or
two day of stress test (SIPP across 4x PRI loop) when d-channels in
/etc/dahdi/system.conf are defined as 'hardhdlc'.

TE420P firmware:
...
TE4XXP version c01a016b, burst ON
Octasic optimized!
FALC version: 00000005, Board ID: 00
Reg 0: 0x30416400
Reg 1: 0x30416000
Reg 2: 0x00000000
Reg 3: 0x00000000
Reg 4: 0x00000101
Reg 5: 0x00000000
Reg 6: 0xc01a016b
Reg 7: 0x00001f00
Reg 8: 0x010200ff
Reg 9: 0x00fd0001
Reg 10: 0x0000004a

Only after a few weeks testing we found out that hardhdlc configuration
seems to cause these crashes (instead of dchan configuration)

hardhdlc also causes the following asterisk/dahdi errors that we don' have
in 'dchan'-mode:
