[asterisk-users] BUG: soft lockup - CPU#1 stuck for 10s! [swapper:0]

[Luis Morales]

The error on system crash is:

Digum Board: TDM2400P
OS: Debian Lenny 5.02
--------------------------------------------------------------------------------------------------------
dahdi_ec_chunk 0x3c/0x200 [dahdi] SS:ESP 00068:F747FE38
KERNEL PANIC NOT SYNCING
--------------------------------------------------------------------------------------------------------

There are any imcompatibility on servers based on quadcore ? or dahdi
not have correct support for this model  ?

Regards,
