I compiled network module sky2 and netconsole into kernel 2.6.35.
Inserted into kernel line:
and ran on a laptop the cmd: "nc -l -u 6666"

This failed to show any output at all.

maybe 3 or 4 screens fulls go by to where boot fails.
I added "boot_delay=15" for next boot.

I only see one sata compiled into kernel: CONFIG_SATA_PMP=y
and I also see no sata's loaded with lsmod in a working
I am going to rebuild again with CONFIG_SATA_AHCI=y
instead of =m as it is Fedora's config (do not know how
it got changed). These modules are loaded in 22.214.171.124:
#lsmod | egrep "ata|ahci"
ata_generic 3427 0
pata_acpi 3227 0
pata_jmicron 2547 0
