Summary: acpi_get_firmware_table return an invalid block of
memory
Kernel Version: 2.6.9-5.EL-ia64
Status: NEW
Severity: normal
Owner: acpi_config-tables at kernel-bugs.osdl.org
Submitter: yukun.chen at intel.com
I find this bug in IPMI driver but after root cause I think it is an ACPI
related bug.So post it here and say sorry in advance if it is not the proper
place for it.
Distribution:
Red Hat Enterprise Linux AS release 4
Hardware Environment:
HPCX 2600
Software Environment:
Problem Description:
Fail to load ipmi_si driver with oop.
More details can be found in PS2.
After debugging with the driver, I found the OOP is caused by an invalid
address.In IPMI driver, we will call acpi_get_firmware_table in try_init_acpi
function to get the information of SPMI table. In this information, there is a
memory pointered by spmi->addr.address and it is invalid. It seems acpi map a
wrong memory and send itout to IPMI but from the boot log of system ACPI is
enabled properly. I think in this case, an error code should be returned by
acpi_get_firmware_table instead of AE_OK, just as what we see in IPMI driver
(See PS1)
Steps to reproduce:
modprobe ipmi_msghandler
modprobe ipmi_si kcs_addrs=0xff5b0ca2
