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.

Update, I edited the .config by hand and added the full path in
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware/"
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.

As this is already at the stage when userspace exists and init has been
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?

I will try that when I next reboot, thanks Jiri

I just did, and ran into 2 things, 1st being an oops or crash that stopped
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?

From a grep FIRM .config:

CONFIG_PREVENT_FIRMWARE_BUILD is not set
CONFIG_FIRMWARE_IN_KERNEL=y
CONFIG_EXTRA_FIRMWARE="radeon/R100_cp.bin.ihex radeon/R200_cp.bin.ihex
radeon/R300_cp.bin.ihex radeon/R420_cp.bin.ihex radeon/R520_cp.bin.ihex
radeon/RS600_cp.bin.ihex radeon/RS690_cp.bin.ihex"
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware/"
CONFIG_LIBERTAS_THINFIRM=m
CONFIG_LIBERTAS_THINFIRM_USB=m
CONFIG_HOSTAP_FIRMWARE=y
CONFIG_HOSTAP_FIRMWARE_NVRAM=y
CONFIG_FIRMWARE_EDID=y
CONFIG_FIRMWARE_MEMMAP=y

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.
