From: Kent Tong To: gdb@sourceware.org Content-Type: text/plain; charset=ISO-8859-1 X-SW-Source: 2013-04/txt/msg00033.txt.bz2 Hi, It seems that after the code being traced disables NMI, gdb will not stop at the next instruction (si) or at breakpoints. Is this a bug or am I missing something? The code is seabios running in qemu i386. Thanks! -- Kent Tong IT author and consultant, child education coach
