2.6.19-rt1 - failed to boot on AMD64

["Mark Knecht" <markknecht@gmail.com>]

Hi Ingo,
  I attempted to get 2.6.19-rt1 going this afternoon but no luck.
First, thanks for the realtime-lsm patch in the kernel. Nice to have
it there.

  OK, so 2.6.19-rt1 starts booting, gets to the point where it see
the keyboard and mouse, and then apparently starts looking for a
remote NFS server? I don't remember seeing this on earlier kernels.

<SNIP>
Root-NFS: No NFS server available, giving up
VFS: Unable to mount root via NFS, trying floppy
VFS: Insert root floppy and press enter
SCSI 0:0:0:0: Direct-Access HP PSC1610  1.00 PQ: 0 ANSI: 2
sd 0:0:0:0: Attached scsi removable disk sda
<SNIP>


At this point the machine just waits and does nothing more. It does
respond to Alt-Ctrl-Del and reboots cleanly.


Here's the basic hardware:

  I'll start going through the kernel config to see if something got
messed up in the make oldconfig step. I've not seen this problem with
any previous -rt kernel. I never ran 2.6.19-rcX so maybe this problem
is something in 2.6.19 and not just the -rt? Maybe I should run 2.6.19
itself and see if it boots?

Thanks,
Mark
