[c-nsp] Cat6500 PM_SCP-SP-2-LCP_FW_ERR_INFORM Bus Asic #0 out of sync error

[Chris Wopat]

Hello, trying to determine if this is is an issue with the line card
(WS-X6148-GE-TX) or the chassis (6509). Out of the blue once every 6
months or so we get:

May 25 07:09:55.108 CDT: %PM_SCP-SP-2-LCP_FW_ERR_INFORM: Module 8 is
experiencing the following error: Bus Asic #0 out of sync error
May 25 07:10:13.107 CDT: %PM_SCP-SP-2-LCP_FW_ERR_INFORM: Module 8 is
experiencing the following error: Bus Asic #0 out of sync error
...

After ~5 minutes of the above errors the card shuts down:

changed state to down
May 25 07:14:59.717 CDT: %LINK-3-UPDOWN: Interface GigabitEthernet8/8,

At this point we have to re-seat the card. Currently running
12.2(33)SXI2a. Trying to determine which (or both) to replace- module
or chassis. Thoughts?
