Hello,

I am often running out of memory. It looks like an ACPI code is guilty:
dast@lili:~$ grep -i acpi /proc/slabinfo
Acpi-Operand 3076 3127 64 59 1 : tunables 120 60 8 : slabdata 53 53 0
Acpi-ParseExt 16 59 64 59 1 : tunables 120 60 8 : slabdata 1 1 0
Acpi-Parse 76 92 40 92 1 : tunables 120 60 8 : slabdata 1 1 0
Acpi-State 1644960 1644960 80 48 1 : tunables 120 60 8 : slabdata 34270 34270 0
Acpi-Namespace 1177 1232 32 112 1 : tunables 120 60 8 : slabdata 11 11 0
dast@lili:~$ free

Actualy the Acpi-State's memory is increasing slowly in minutes:
Acpi-State 16176 16176 80 48 1 : tunables 120 60 8 : slabdata 337 337 0
Acpi-State 18816 18816 80 48 1 : tunables 120 60 8 : slabdata 392 392 0
Acpi-State 19200 19200 80 48 1 : tunables 120 60 8 : slabdata 400 400 0
Acpi-State 20160 20160 80 48 1 : tunables 120 60 8 : slabdata 420 420 0

I am not familiar with kernel sources, but i can do c pretty well.
BTW: Bios says i have 1024MB, but kernel sees 899MB :-?. The system is
pure HP nx6325. It happens with all the recent kernels .18-rc* .17.* and
debian's distribution 2.6.17-1-amd64-k8-smp.

Please Cc: to me, I read lkml only when I have a good mood.
