Hi,

looks like I'm catching this one:

Jul 19 16:07:15 arak kernel: try_to_free_page: free pages 1008kB, async pages 0kB
Jul 19 16:08:56 arak kernel: try_to_free_page: free pages 1020kB, async pages 12kB
Jul 19 16:12:04 arak kernel: try_to_free_page: free pages 1012kB, async pages 4kB

Using your current patch I always get this after booting and running my
favourite test. Usually only once but this time three times. I've not seen
it any other time - yet;) Booting with profile=2.

werner-test &> results

And werner-test is:
#!/bin/sh
strace -c bonnie
readprofile -r ; bonnie ; readprofile | sort -rn

Other patches I am using are:
ncr53c8xx-2.3c scsi driver
lnz pre-2.0.31 scsi patch

Sytem P-133, 64MB dram, ncr810a + jaz 1GB (unmounted), Symbios ncr53c875 +
Barracuda 4.3GB st15150n.
