recently I installed the latest kernel 4.1.0-rc3 in my Ubuntu 14.04 LTS 64-bit.When I did reboot after make install, it is getting stuck after the grub listing the following error mentioning that it has been calling CRDA to update world regulatory domain for 4-5 times-
* cfg80211:Exceeded CRDA call max. attempts. Not calling CRDA [234.021955] random: non-blocking pool is initialized Gave up waiting for root device. Common problems: - Boot args (cat /proc/cmdline) - Check rootdelay= (did the system wait long enough?) - Check root= (did the system wait for the right device?) - Missing modules (cat /proc/modules; ls /dev) ALERT! /dev/sda1 does not exist. Dropping to a shell! BusyBox v1.21.1 (Ubuntu 1:1.21.0-1ubuntu1) built-in shell (ash) Enter 'help' for a lost of built-in commands. (initramfs)*
I checked for the solution in the following thread and made all the three attempts mentioned in one of the answers, but it still didn't help in correcting the error.
