Note the time, it kills quite close to a whole minute there, which at
first would appear to be because there is not yet a mounted /lib
filesystem to suck it from. I didn't build an rc1, but rc2 also
suffers from this. 2.6.32.2 does not do this although its firmware
request takes place at the same point. So it doesn't look like it is
the lack of a mounted filesystem after all.
FWIW, because it was a hot reboot, the patch_level reported is the
correct level.
I am also seeing some complaints about my Audigy2 sound card, but what
I saw during the boot, never made it to the messages log. Something
about guessing at the proper config, but I did hear kde sign on when
x started.
Thanks Linus.

which was just 'firmware', and rebuilt. No difference. I still get
the 60 second hang. FWIW, this particular setting isn't visible in a
make xconfig.
started, it might well be delay of some userspace stuff, not directly
kernel.
Does alt-sysrq-t at the time it is stuck give any clue?
the shutdown and I was forced to use the hdwe reset button. I rebooted to
2.6.32.3 which worked nominally correct, then to 2.6.33-rc3 again, and
played 10,000 monkeys on the keyboard while it was sitting there waiting
for the /lib/firmware/amd-ucode/micrococode_amd.bin for 60 seconds, with
no apparent effect.
I am not convinced my wireless keyboard is alive at 0.6 seconds into the
boot procedure. Or I was using the wrong key for 'sysreq' as susch a
labeled key does not exist on this logitek cordless keyboard.
What line in the .config file actually specifies the path it is supposed to
be searching to find this file?

Is something missing above?
If I want to add the amd-ucode/microcode_amd.bin to CONFIG_EXTRA_FIRMWARE,
I will have to do it by hand as the xconfig editing function for that line
seems to have gone away. That list of radeon stuff hasn't been touched in
nearly 2 years. However, I will do that and report eventually.
Or did the firmware loader itself get broken?
Thanks Jiri.
Update: Fixed for me.
I left that line in the .config with the amd-ucode/microcode_amd.bin added as discussed above, but I finally grokked that the kernel trees firmware/amd-
ucode directory was not there, so I moved a copy of the microcode_amd.bin into that directory and re-ran my makeit script. No errors during the make, and the 1 minute stall problem at .6 seconds into the boot is now fixed.
2 Silly Q's though:
1. Can this file not be distributed as part of the kernel tarball?
2. Why did this Just Work(TM) for 2.6.32.3 and all previous kernels when the only copy on the system was in /lib/firmware/amd-ucode, but not for 2.6.33-
rcany so far? FWIW, 2.6.32.3/firmware has no amd-ucode subdir at all!
