Tried that and no difference. Note that 2.6.11.x with bs4 doesn't compile with this option showing unless you set FRAME_POINTER to n. You get an error such as: kernel/built-in.o(.text+0x83f4): In function `profile_tick': kernel/profile.c:387: undefined reference to `profile_pc' The only way I could find to set this option to n was hacking the autoconf.h file... So still no 32 bit UML... will try 64 bit (once I get access to the 64 bit compiler) and see if I can get that to work.... ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
