Description
The sparc64 kernel hangs during the fault1 test, which is not the expected behavior. The expected behavior is kernel panic.
Note:
See TracTickets
for help on using tickets.
Fixed in changeset:head,202.
When the kernel was trying to dump the istate structure during the bad trap caused by the test1
testcase, it tried to map the address in program counter to a symbol. Because the symbol table was
not aligned, it got a memory alignment trap, for which it was trying to dump istate. This generated
another memory alignment trap and so on and so forth.
