Bug#738575: Access to a Galileo board

[Thomas Karmann <thomas@krmnn.de>]

Hi,

I patched out the lock instruction via hexedit and the segfaults are gone!

before:

=>  507b:       f0 0f b1 8b 94 21 00    lock cmpxchg %ecx,0x2194(%ebx)

after:

    507b:       90                      nop
    507c:       0f b1 8b 94 21 00 00    cmpxchg %ecx,0x2194(%ebx)


Might be a bug in the CPU itself?


With kind regards
Thomas
