Hi Experts,
All was working fine till now. But because the cpu cores were not utilized completely, I increased the 'maximum number of cpu' in the make menuconfig under /usr/src/linux from 32 to 48. My server has 2 Processor of 12 cores each and with hyperthreading TURNED ON, it makes it to 48.
I changed the value to 48 and then recompiled the kernel using :-
Quote: | make -j48 && make -j48 modules_install |
I then copied the bzImage to /boot . Then I and ran Quote: | 'grub2-install /dev/sda' and 'grub2-mkconfig -o /boot/grub/grub.cfg' | . All went fine without any errors. I rebooted my server and during the boot time, I see it loading from the new image, but it gets stuck after some time.
It passes all the checks and then gets stuck at Quote: | '' Configuring Kernel parameters '' . | and just sits them for all.
I am not sure how to get this fixed and need your expertise on it.
Appreciate all your help in advance. |

Screenshot/screen capture (via digital camera) would be helpful.
I don't think building via -j XXX will create a bad kernel unless there's some dependency fault, which likely should have been detected earlier with fewer cpus...
Also it's unneeded to rebuild the bootloader each time you make a new kernel.
You have a rather exotic machine that perhaps needs to be dealt with directly on the LKML if it turns out to be a kernel bug. _________________ Intel Core i7 2700K/Radeon R7 250/24GB DDR3/256GB SSD
