Re: Oops with IPMI and ACPI disabled on command line

Yes, I noticed this recently, too. It seems to be an ACPI bug, but I'm
not 100% sure. Here's my post to lkml:
In 2.6.12-rc4, I added acpi=off to the kernel command line and it
panic-ed in acpi_get_firmware_table, called from the IPMI driver.
The attached patch fixes the problem, but it still spits out ugly
"ACPI-0166: *** Error: Invalid address flags 8" errors. So I doubt the
patch is right, but maybe it points to something else.
Is it legal to call acpi_get_firmware_table if acpi is off? If not, how
can I tell that acpi is off?

Hi,
I encounter an Oops with IPMI modules using acpi=ht|off,
I fixed it (only the Oops, IPMI is still not available on the system),
by two patches which follows.
Here is the Oops messages for reference:
