Hi Alexey, Thank you for your help. I have raised the bug #7163 with the DSDT capture from the /proc subsystem. I will keep digging to see if I can find a workaround. So far, all I can do is disable ACPI to stop the memory leak. :-( Best regards, Roger > -----Original Message----- > From: Alexey Starikovskiy [mailto:alexey_y_starikovskiy@xxxxxxxxxxxxxxx] > Sent: 15 September 2006 22:08 > To: Roger Lucas > Cc: linux-acpi@xxxxxxxxxxxxxxx; 'Suietov, Fiodor F' > Subject: Re: Kernel eats memory with LG-81 motherboard , acpi_operand > possible culprit? > > Please open bug against AML interpreter (same category as 6514) and put > your original DSDT and dmesg there. > > Thanks, > Alex. > > Roger Lucas wrote: > > Hi Alexey, > > > > I've installed the latest 2.6.17.13 kernel (compiled from kernel.org > source > > that I downloaded earlier today) and the "acpi_operand" field in > > "/proc/slabinfo" is still steadily rising.
