Hello.

I just gave 2.6.30-rc a try, taken from Linus git, tag v2.6.29-rc8.
And this one does not want to boot on my test machine which is an
AMD X2-64 with AMD780G chipset.  Neither 64 nor 32bit kernel boots.
I even tried in kvm virtual machine, -- same effect.  It freezes right
after displaying "Verifying BIOS data successful" message -- nothing
more is on the screen.

I did `make silentoldconfig' based on my current 2.6.29 configs.  In
the configs there are the following changes:
  - quite some changes in various new/changed drivers (which should
    not affect what I'm seeing)

  - decompression: I've no idea what compression it used before, but
    `make oldconfig' offered gzip by default which I accepted. Should
    I try bzip2 instead?

  - changed HZ from 100 to 300

  - also the following which I don't think I touched:

   -X86_INTERNODE_CACHE_BYTES=128
   +X86_INTERNODE_CACHE_BYTES=64

   -X86_L1_CACHE_BYTES=128
   +X86_L1_CACHE_BYTES=64

   -X86_L1_CACHE_SHIFT=7
   +X86_L1_CACHE_SHIFT=6

I'm trying different compression method for now.  If it will solve
this issue, my conclusion will be that the default value is  wrong
and - oh well - expect more reports/questions like this one :)

The rest of the system is not very interesting I think: the kernel
config is pretty generic (most stuff is in modules), compiler is
default on Debian Lenny (4.3.2-1.1).

Thanks!
