The configuration item CONFIG_DEBUG_ICACHE_CHECK:

• prompt: Check Instruction cache coherency
• type: bool
• depends on: ( CONFIG_DEBUG_KERNEL ) && ( CONFIG_DEBUG_HWERR )
• defined in arch/blackfin/Kconfig.debug
• found in Linux kernels: 2.6.24–2.6.36

Say Y here if you are getting weird unexplained errors. This will ensure that icache is what SDRAM says it should be by doing a byte wise comparison between SDRAM and instruction cache. This also relocates the irq_panic() function to L1 memory, (which is un-cached).
