Hi!
I've stumbled across this WARNING: when booting 2.6.28 + patch
on my alpha. This happens consistently (i.e. on every boot) and
keeps happening while the machine is booted:

Here's a full dmesg:
http://eric.schwarzvogel.de/~klausman/kernel/2.6.28/alpha/dmesg_post_boot.txt
Note that it happens again later in the same dmesg. The messages
always mention page allocation at the top of the trace.
The patch mentioned above is commit
1684f5ddd4c0c754f52c78eaa2c5c69ad09fb18c which fixes compilation
on alpha (see http://bugzilla.kernel.org/show_bug.cgi?id=12289)
The patch I used is here:
http://eric.schwarzvogel.de/~klausman/kernel/2.6.28/alpha/pci.patch
Here's my config:
http://eric.schwarzvogel.de/~klausman/kernel/2.6.28/alpha/config.txt
shortened by grep ^C:
http://eric.schwarzvogel.de/~klausman/kernel/2.6.28/alpha/config-shortened.txt
The normal console output (catched via serial console) is here:
http://eric.schwarzvogel.de/~klausman/kernel/2.6.28/alpha/console_output.txt
The machine in question is a Samsung UP1500. CPU is EV68AL on an
ALI chipset (ali15x3).
Last kernel to work perfectly is a vanilla 2.6.27.10.
Before I dig into a rather time-consuming bisect, I'd like to
hear informed opinions :)
Regards & TIA,
Tobias

For me they are occurring during invocation of 'lvm vgchange -a y'.
The first call also fails, i.e. '0 volume groups activated',
while a second call succeeds and activates both of the VGs it should handle.
The traces above were taken from dmesg. They are not the first ones as there
are quite a lot of them (perhaps one for every block device checked by
the lvm tool?) and so the initial ones already escaped the message buffer.

The problem is that alpha allocates some VMALLOC space very early
on boot, but the new VM allocator doesn't know about this.
I've posted a fix few days ago:
