I'm new to the KEXEC/KDUMP world - just started out today. I believe
that I have things set up right, but I'm running into two issues:
1. A few seconds into the boot, I see:

2. Very soon thereafter, I start seeing:
[ 4.671112] sda:<3>ata1: EH in ADMA mode, notifier 0x1
notifier_error 0x0 g0
[ 34.681112] ata1: CPB 0: ctl_flags 0xd, resp_flags 0x1

[ 35.251112] ata1: EH complete
This goes on "forever" - and the system fails to boot.
This script is used to set up kexec:
root="root=/dev/sda1"
gen_args="1 irqpoll maxcpus=1 reset_devices"
bannor_args="acpi=off console=tty0 console=ttyS2,115200n8"
/usr/local/sbin/kexec -l /boot/vmlinuz-2.6.25-rc8-bannor-kexec \
--append="${root} ${gen_args} ${bannor_args}"
Some other notes:
o I have the kernel gen'd w/out an initrd
o Kernel is gen'd w/out CONFIG_SMP
o I added the 'acpi=off' as one site I google'd had that as a possible
fix for a problem like this.
I do not know if the two problems mentioned above are related, but in
any case, I'm wondering if there are any pointers out there to help get
this going.
I have the output from 'lspci' and the console log during a failed boot
