AS Rock Z77E-ITX + Intel SSD 330 Series segfaults under load

Hi,

I just finsihed installing a new system with an AS Rock Z77E-ITX mini ITX mother board (Intel Z77) and an Intel 330 Series 120GB SSD.

The setup is EFI+GPT+LUKS+LVM+EXT4 and it segfaults if I put heavy io load on the SSD.

I have tried to remove as many components as I can and it still segfaults in the same way.
So to reproduce it a simple as possible I run bonnie++ on an empty ext2 partition (which I guess is mounted using the ext4 subsystem):

$ mkfs.ext2 /dev/sda2
$ mount /dev/sda2 /mnt
$ bonnie++ -f -d /mnt
Writing intelligently...Segmentation fault

and at the same time..

$ journal -f

I'm guessing its either a bug in the ext4 sub system, problems with the mb/hd-controller, problems with the SSD or a combo
Any suggestions are super welcome.

Re: AS Rock Z77E-ITX + Intel SSD 330 Series segfaults under load

Sure it isn't a hardware issue with the SSD?  Are you able to repeat the conditions that cause the panic using another OS such as a live Ubuntu session for example?

Re: AS Rock Z77E-ITX + Intel SSD 330 Series segfaults under load

I just tried with the Ubuntu 12.04 LTS server installer iso image. I could not see the dmesg output but the system froze hard after a minute of writing to the SSD with dd. I guess I should return the SSD and try with a new one. Is it common that a faulty SSD takes down the system? Feels sloppy.
