I'm running linux kernel 2.6.30 with kgdb8250 on x86_64
When I set a breakpoint and continue, I get a 'error accessing memory
address' error:

Program received signal SIGTRAP, Trace/breakpoint trap.
kgdb_breakpoint () at kernel/kgdb.c:1807
1807            wmb(); /* Sync point after breakpoint */
(gdb) b fget
Breakpoint 1 at 0xffffffff803057d9: file
/volumes/sdb1/linux-2.6.30/arch/x86/include/asm/current.h, line 14.
(gdb) c
Continuing.
Warning:
Cannot insert breakpoint 1.
Error accessing memory address 0xffffffff803057d9: Unknown error
18446744073709551615.

Any idea why this is happening?

Thanks,
-Joel
