Hi, Intel folks. I've just found the bug in rsutils.c which double
free(); AcpiUtRemoveReference() and ACPI_MEM_FREE(). Here is a fix.
Index: rsutils.c

Cleanup:
- ACPI_MEM_FREE (ByteStream);
return_ACPI_STATUS (Status);
}
I suspect that this should be removed in ACPICA 20010831-to-20010920
changes.
Matsuda-san, thanks. I missed the original mail in current ML written
by brian.
Thanks
