I tried to compile the patch on top of 2.6.13-rc4-mm1, it applied with a fe= w=20 offsets, but it looked ok. Here is the error I get when I compiled it: CC arch/x86_64/kernel/traps.o arch/x86_64/kernel/traps.c: In function `show_trace': arch/x86_64/kernel/traps.c:228: warning: implicit declaration of function=20 `print_traces' arch/x86_64/kernel/traps.c:228: error: `task' undeclared (first use in this= =20 function) arch/x86_64/kernel/traps.c:228: error: (Each undeclared identifier is repor= ted=20 only once arch/x86_64/kernel/traps.c:228: error: for each function it appears in.) make[1]: *** [arch/x86_64/kernel/traps.o] Error 1 I took a look at the traps.c file, but couldn't find any solution, as there= is=20 no print_traces function and task variable too in this section. dominik --nextPart2655351.RW4KK5tHXM Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2-ecc0.1.6 (GNU/Linux) iQCVAwUAQvNROgvcoSHvsHMnAQIWLwP+O51sz/EyXEWjNbDHal4SuPNUepuyPpF+ SseRJAymy41nsklYqR2Y+x2tHYusN+DwVTUb3zcn2YG4h+/A6yqQPZINzJZMu847 GjyeuuyDV250zl6nSFAlGZJuD+b1KKni9UKFjzd0JPV+R6qvcV+4cNdxkF8Bx9Fy uob3j7LPOYQ= =vsfW -----END PGP SIGNATURE----- --nextPart2655351.RW4KK5tHXM--
