Read the "Linux kernel Development" 1st edition page 175 > about vmalloc(), there I got this raw conclusion > Before we run off making conclusions about what caused the panic, it would be good to learn more about the problem: dmesg/oops output (if available), source code that is calling vmalloc, etc. It's always best for me to assume that I did something stupid to cause an error (which is 99+% the case) than look for explanation in the kernel. -- Bob > regards > > Mulyadi > > > -- > Kernelnewbies: Help each other learn about the Linux kernel. > Archive: http://mail.nl.linux.org/kernelnewbies/ > FAQ: http://kernelnewbies.org/faq/ > > -- Kernelnewbies: Help each other learn about the Linux kernel.
