Hi all,

In my log file, I got this message.
Sep 10 20:10:15 localhost kernel: allocation failed: out of vmalloc space - use vmalloc=<size> to increase size.

Does anyone knows how to increase the vmalloc size? I have a 4GB RAM but my vmalloc size is only around 250MB. here's the output of meminfo.

Thanks in advance,

I have added a vmalloc option in grub.conf.
something like:

kernel /boot/vmlinuz ro root=/dev/ram1 ramdisk_size=136000 rhgb quiet vmalloc=512M

reboot, still it didn't increase the vmalloc size.

-bash-3.00# cat /proc/cmdline
ro root=/dev/ram1 ramdisk_size=136000 rhgb quiet

the vmalloc option has not been passed to the kernel, any idea hot to do it?

thanks,
warren
