Mini kernel ( kexec ) is having boot time errors

[Dharmosoth Seetharam]

Hi,

I am getting the following error when my system gets panic it tries to
switch into mini kernel ( pre-loaded one).

pre-loaded the mini kernel with the following option.


/*
kexec -p /usr/u/seetharam/bin/vmlinux.10888 --initrd=/boot/initrd-2.6.20-aruba_0.0.10888.img --command-line=" root=/dev/system/rootvol console=ttyS0,19200n8 SPEED=19200 init 1 maxcpus=1 irqpoll " --serial-baud=19200 --console-vga  --console-serial --args-linux

*/

[root at tc210 root]# mount | grep root
/dev/system/rootvol on / type xfs (rw,sync)

I have given the cmd parameter "irqpoll" but, suggesting me to use irqpoll...:)

Please help me in this regards.



Thanks,
