error message in question. Higher levels of chattiness may be used if required.

Hello!

Doing kernel testing, occasionally I started to get messages:

mator@ttip:~/linux-2.6$ make -j olddefconfig; nice make -j20 && nice make -j20 modules # # configuration written to .config # SYNC include/config/auto.conf.cmd make[1]: /bin/sh: Bad address UPD include/generated/compile.h UPD include/config/kernel.release UPD include/generated/utsrelease.h

It is not always "bad address" is shown, next time i run "make olddefconfig" it does not shows, but sometimes it shows... How do i debug this ?

Sounds like bad RAM to me

is a VM... and if it would be "bad ram" there would be random program segfaults and kernel OOPS all around... But thanks anyway, going to use "V=1"
