The easiest way to fix this is to decrease the virtual space of the kernel at boot time. To do this, do the following commands: # cd /boot/grub/ # vi grub.conf Edit the grub conf file by adding the following parameters at the kernel command line: vmalloc=384M After modifications, restart the driver by: # dis_services restart |
