Spurious I2C Interrupts on MPC8349E

We have a board with MPC8349E running with VxWorks 5.5.
We got a sporadic (1 time, not reproducible) issue whereby we got a plethora of I2C1 interrupts which caused a kernel workQ panic.

In a usual run, we never get these interrupts, and we never expect it to come.
How do we continue to debug this issue? Could it be that i2c controller somehow got into a bad shape? What info can help to further debug?
