I've got an IPMI 1.5 card from SuperMicro (so it has the backported
IBM serial over lan capability that is normally in 2.0) in a X5DPR-TP+
motherboard with a single P4 HT Xeon CPU. Using kernel 2.4.25 I am
able to utilize the serial over lan console of the IPMI card without
problems (I can see the bootup all the way to the login). However,
with a 2.6.7 kernel, the console ceases to print right after
"Initializing CPU#0"... I've been searching the list and the web all
weekend trying to figure out what is going on, but most of the
problems people have had that are similar relate to failing to
configure VGA_CONSOLE, but as you'll see, that is not the case in my
config (config attached to this message):

# CONFIG_NETCONSOLE is not set
CONFIG_VT_CONSOLE=y
CONFIG_HW_CONSOLE=y
CONFIG_SERIAL_8250_CONSOLE=y
CONFIG_SERIAL_CORE_CONSOLE=y
CONFIG_VGA_CONSOLE=y
# CONFIG_MDA_CONSOLE is not set
CONFIG_DUMMY_CONSOLE=y

The machine boots all the way up, but that is not visible on the console.

Here is everything I see on the console:

ACPI: LAPIC (acpi_id[0x01] lapic_id[0x01] enabled)

Here is what is in my dmseg immediately after boot (note: the first
part of ACPI is cut off in the dmesg as well):
