[LinuxBIOS] lzma compression and filo/etherboot payloads in buildrom

[Ward Vandewege]

Hi all,

I seem to have a problem when trying to use a lzma pre-compressed payload in
buildrom in combination with an etherboot (or filo) payload. Things work fine
with a kernel or LAB payload.

I've attached the LinuxBIOS Config.lb I used, and the boot output for
etherboot. I recall having similar problems with a filo payload.

If I disable CONFIG_COMPRESSED_PAYLOAD_LZMA and CONFIG_PRECOMPRESSED_PAYLOAD
in Config.lb and disable the LZMA compression in buildrom's kconfig the
Etherboot payload works just fine.

Am I doing something stupid?

Thanks,
Ward.

I just tried it with serengeti_cheetah, and it worked for me with just a
fallback image. I've attached my Config and bootlog.

I noticed that you have CONFIG_COMPRESSED_PAYLOAD_LZMA and
CONFIG_PRECOMPRESSED_PAYLOAD set in your Failover image, even though there
is no official payload.

I couldn't see anything else, but I hope this helps.

Weird!

Yeah, removing those does not help; same problem:
