In fact, that was exactly what we just did.
Disabled it in BIOS first and it did not help. Removed the SMP from OS and now it works as expected.

smp_rep_general
SMP_REP_GENERAL(8) SMP_UTILS SMP_REP_GENERAL(8)
NAME
smp_rep_general - invoke REPORT GENERAL SMP function
SYNOPSIS
smp_rep_general [--brief] [--changecount] [--help] [--hex] [--interface=PARAMS] [--raw] [--sa=SAS_ADDR] [--verbose] [--version] [--zero]
SMP_DEVICE[,N]
DESCRIPTION
Sends a SAS Management Protocol (SMP) REPORT GENERAL function request to a SMP target. The SMP target is identified by the SMP_DEVICE and
the SAS_ADDR. Depending on the interface, the SAS_ADDR may be deduced from the SMP_DEVICE. The mpt interface uses SMP_DEVICE to identify a
HBA (an SMP initiator) and needs the additional ,N to differentiate between HBAs if there are multiple present.
OPTIONS
Mandatory arguments to long options are mandatory for short options as well.
-b, --brief
reports (prints to stdout) only a few important fields from the response.
-c, --changecount
reports (prints to stdout) the value of the expander change count field from the response. The value is printed in decimal and is in
the range 0 to 65535. Only expanders compliant with SAS-1.1 (and earlier) should yield 0. [Expanders compliant with SAS-2 (and
later) should set the "long response" bit in the REPORT GENERAL response to 1.]
-h, --help
output the usage message then exit.
-H, --hex
output the response (less the CRC field) in hexadecimal.
-I, --interface=PARAMS
interface specific parameters. In this case "interface" refers to the path through the operating system to the SMP initiator. See
the smp_utils man page for more information.
-r, --raw
send the response (less the CRC field) to stdout in binary. All error messages are sent to stderr.
-s, --sa=SAS_ADDR
specifies the SAS address of the SMP target device. Typically this is an expander. This option may not be needed if the SMP_DEVICE
has the target's SAS address within it. The SAS_ADDR is in decimal but most SAS addresses are shown in hexadecimal. To give a number
in hexadecimal either prefix it with '0x' or put a trailing 'h' on it.
-v, --verbose
increase the verbosity of the output. Can be used multiple times
-V, --version
print the version string and then exit.
-z, --zero
zero the Allocated Response Length field in the request. This is required for strict SAS-1.1 compliance. However this option should
not be given in SAS-2 and later; if it is given an abridged response may result.
EXAMPLES
See "Examples" section in http://sg.danny.cz/sg/smp_utils.html
CONFORMING TO
The SMP REPORT GENERAL function was introduced in SAS-1, with small additions in SAS-1.1 . There have been a large number of additions in
SAS-2 .
