Workaround is to reload the principal, it will stop the ASIC interrupt for the time being - until the next occurrence.
Once the Principal is reloaded, another switch in the VCS will take over to perform the principal role to process the ISL link initiation for the affected switch(es) to rejoin.
The fix is to upgrade to the firmware version containing the code fix.
Defect624394: 000624394 Continuous ASIC error seen with VDX 6940 is fixed in NOS 6.0.2c
