This fails to come up on my development machine, apparently because it
has trouble accessing the SATA hard disks.
Hardware: Intel Pentium D940, Intel DQ965GF board, two SATA hard disks.
Some unusual things I noticed during the boot process:

- a message "doing fast boot" that looked unfamiliar; unfortunately
  it scrolled off too quickly to note its context

- for each of the two SATA ports in use, a message
  "SATA port is slow to respond, please be patient"
  accompanied by about 10 secs wait

- it actually got past the point where it mounts the root file system,
  so it must have thought it could access the disks

- finally, the system hung completely after the SUSE startup messages

  Setting current sysctl status from /etc/sysctl.conf
  net.ipv4.icmp_echo_ignore_broadcasts = 1

  with a dead keyboard and I had to hit the Win^Wreset button.

- After rebooting into 2.6.24-rc8 (which works fine), nothing had been
  written to the disks, not even the dmesg output which SUSE usually
  dumps into /var/log/boot.msg early during startup.

Before I try booting that kernel again, any instructions on what to
watch out for? Is netconsole usable again? Other ideas?

Tilman
