Hi Rami, kexec -p executes normally. Then when I do echo c > /proc/sysrq-trigger, screen freezes and nothing happens. But, There is a small thing which is different when I execute echo c > /proc/sysrq-trigger without kexec -p, the caps lock light blinks. But in case of kexec -p ... and cho c > /proc/sysrq-trigger, the caps lock doesn't blink. Some time screen messes up. regards, Ronit On Sat, Mar 5, 2016 at 11:01 PM, Rami Rosen [off-list ref] wrote:
Hi Ronit, Can you please tell what happens when you ran the "kexec -p" that you mentioned ? Do you see any message on screen ? Does it hang immediately ? Regards, Rami Rosen ?????? 6 ???? 2016 05:23, "Ronit Halder" [off-list ref] ???:quoted
When I am doing normal load of kernel using kexec, it works. #kexec -l /boot/vmlinuz-4.3.0-crash+ --initrd=/boot/initramfs-4.3.0-crash+.img --append="root=/dev/mapper/fedora-root 1 irqpoll maxcpus=1 reset_devices" #kexec -e But, when I am doing load on panic using kexec, it isn't working. #kexec -p /boot/vmlinuz-4.3.0-crash+ --initrd=/boot/initramfs-4.3.0-crash+.img --append="root=/dev/mapper/fedora-root 1 irqpoll maxcpus=1 reset_devices" #echo "1" >/proc/sys/kernel/sysrq #echo c > /proc/sysrq-trigger What am I doing wrong? _______________________________________________ Kernelnewbies mailing list Kernelnewbies at kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
