Agreed, but some recoverable errors are not currently checking the exception table. For example, sys_query_module = 0xe000000000a64000, id 0xc000000000a64000 (same address, but region 6) fails with 'General Exception: IA-64 Reserved Register/Field fault (data access)'. The more resilient I can make kdb, the better I like it, hence my wish to add recovery to ia64_fault().
