19b58: 85 04 (P5:5) = [SP++];

19b5a: 10 00 RTS;

Hmmm... It's failing on the UNLINK instruction?

Lets check the stack:

FP : 00deaf00 USP : 00deaef4

00deaee0: 00000000 00000000 00000000 00000000

00deaef0: (00deaf10)[00d8d544] 0000002f 00deaf9c

^^^^^^^^

stack pointer

00deaf00: (00deaf18)<00dcd190> 00dcd1c4 00dcd1c4

^^^^^^^^

Frame pointer

00deaf10: 00deaf2c <00d95202>(00deaf2c)<00d95254>

00deaf20: 00000000 00000000 00000000 (00000000)

00deaf30: 00000000 00dcd1c4 00000000 00000000

00deaf40: 00000000 00000000 00000000 00000000

00deaf50: 00000000 00000000 00000000 00dcd184

So the frame pointer does point to a valid frame pointer. and the SP is a valid

32-bit aligned value. The value after the frame pointer (which gets loaded into

RETS) is a valid address - 00dcd190 - <0x00dcd190> [ modprobe + 0x4d150 ]

and points to a real return address.

0004d144 <__init>:

4d144: 00 e8 03 00 LINK 0xc; /* (12) */

4d148: fd e3 ae 97 CALL 0xa4 <_frame_dummy>;

4d14c: fe e3 f2 64 CALL 0x19b30 <___do_global_ctors_aux>;

4d150: 01 e8 00 00 UNLINK;

4d154: 10 00 RTS;

a little puzzling...

--- Robin Getz 2008-07-20 04:24:01

Hmm...

I think I might know what this is - checking with design.... (which is always a

bad sign).

Assigning to me.

--- Robin Getz 2008-07-22 16:43:13

This will be described with a new anomaly: 05-00-0426 which is similar to

05-00-0425 (Spurious Hardware Error from an Access in the Shadow of a

Conditional Branch).

I'm working on a workaround to check into the branch.

--- Robin Getz 2009-01-05 13:33:26

A fix went into the toolchain.

This can be closed.
