Hi,

I build linux-2.6.33-rc2 on a Debian/sid 32-bit host.
Unfortunately, this kernel falls in an unusable state (sort of loop)
and does not a normal startup.

With this setting (see below), I hoped to catch the early
boot-messages (but, no success):

# cat /etc/default/bootlogd
# Run bootlogd at startup ?
BOOTLOGD_ENABLE=Yes

Finally, I could take a picture [1].
It seems to be that latest ACPI patches are breaking my system (speculating).

Q: How can I log such early boot (error) messages to give a detailled log?

Hope this helps fixing the problem.

Kind Regards,

you can try(if you have the port)
ohci1394_dma=early or the usb
early logging located in kernel hacking.

but if this thing is hitting way early it
might be a bit more tricky.

if you can try a bisect from the bad
kernel to the good.
