Hi Dirk,
when I set a breakpoint to address 0x80000180 ("b *0x80000180"), this
works as expected. So do breakpoints to symbolic addresses in the
Linux kernel.
"info breakpoints" shows address 0xffffffff80000180 for the first example.
Maybe "b *0xbfc00380" works for your case. If it does, your mips-gdb
is somehow strange.
Regards
Stefan
