Subject: 2.6.34 Northbridge Chipset Errors on HP Proliant 4 x Opteron in
x86_64 mode
On a 4 x Opteron HP Proliant Server with a CCISS array controller in
x86_64 mode, under very heavy (saturated) disk IO, 2.6.34 reports the
following error:
Jun 29 02:02:08 kernel: Northbridge Error, node 0, core: 0
Jun 29 02:02:08 kernel: ECC/ChipKill ECC error.
Jun 29 02:02:08 kernel: EDAC amd64 MC0: CE ERROR_ADDRESS= 0xc7358280
Jun 29 02:02:08 kernel: EDAC amd64: get_channel_from_ecc_syndrome:
error reading F3x180.
Jun 29 02:02:08 kernel: EDAC MC0: CE page 0xc7358, offset 0x280,
grain 0, syndrome 0xa4c1, row 3, channel 0, label "": amd64_edac
Jun 29 02:03:21 kernel: Northbridge Error, node 0
Jun 29 02:03:21 kernel: ECC/ChipKill ECC error.
Jun 29 02:03:21 kernel: EDAC amd64 MC0: CE ERROR_ADDRESS= 0xc7358280
Jun 29 02:03:21 kernel: EDAC amd64: get_channel_from_ecc_syndrome:
error reading F3x180.
Jun 29 02:03:21 kernel: EDAC MC0: CE page 0xc7358, offset 0x280,
grain 0, syndrome 0xa4c1, row 3, channel 0, label "": amd64_edac
The error is reproduceable by subjecting the server to excessive disk
loads > 350 MB/S stream to disk.
