Erm, this doesn't look good:
movl $GPROC0_SEL*8, %esi /* GSEL(entry, SEL_KPL) */
ltr %si
#define GPROC0_SEL 4 /* Task state process slot zero and up */
Thus, %esi should be 32 == 0x20, not 0x100. :( I have no clue why that is
screwed up, unless something is overwriting your code segment. Can you panic
it and do an x/i of sw1b+0x72? It should look something like this:
121: be 20 00 00 00 mov $0x20,%esi
126: 0f 00 de ltr %si
