Run zttool and see if you the T1 card is missing interrupts. If so, put the following statement in your rc.local :
# unmask interrupts /sbin/hdparm -u1 /dev/hda This will tell the ide driver not to mask interrupts while servicing disk i/o and the missing interrupts on your T1 card will likely go away. If this isn't the problem, zttool might still give you a hint if there are problems on the PRI itself.
