bonnie on md+xfs causes reboot

[Matt Garman]

I have a raid5 md device, on top of which is an xfs filesystem. When I run the bonnie++ benchmark using this filesystem, it causes the computer to reboot.

Recently I changed the hardware: from an Intel Q35 motherboard with an E5200 CPU to a Gigabyte GA-MA74GM-S2 (AMD 740G/SB700) motherboard and 4850e CPU. I never experienced this with the previous hardware.

The md device is built from four Western Digital 7500AAKS 750 GB 7200 rpm SATA drives. The drives are connected to two 2-port Silicon Image SiI 3132 PCIe cards.

$ cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md1 : active raid5 sde1[0] sdh1[3] sdf1[2] sdg1[1]
      2930279808 blocks level 5, 64k chunk, algorithm 2 [4/4] [UUUU]

md0 : active raid5 sdd1[0] sdb1[3] sda1[2] sdc1[1]
      2197715712 blocks level 5, 64k chunk, algorithm 2 [4/4] [UUUU]
      [===============>.....] resync = 75.3% (552091520/732571904) finish=93.4min speed=32198K/sec

md0 is the device on which the reboots happen; I haven't tried running bonnie on the md1 device.

Every time this reboot occurs, the array has to be resync'ed.

But I also compiled 1.93c from source; it has the same problems.

This is a hardware problem. I contacted Gigabyte, and the PCIe x16 slot is only for video cards.
