I have problem about HP DL360 G7 with SUSE 11 SP1 upgrade to SP4 .
HP server have below problem few days ago.
The cause may be a non-maskable interrupt (NMI) generated by the Intel Performance Monitoring Unit (PMU) that is not properly handled by the Linux kernel.
An indicator of this type of error is the following message in the IML log at the time of the hang or crash
LOG: An Unrecoverable System Error (NMI) has occurred (System error code 0x00000000, 0x00000000)
HP engineer told us need to updated to SLES 11 SP2 or later.
but I go to find SP4's release notes , can't find information about fix this kernel bug.
