Re: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2 frozen

["Greg Cormier" <gcormier@gmail.com>]

I'd like to hop in on this, and add my similar problem. This is my
first post so please excuse me if I'm doing something wrong.

I've been having issues recently (couple of weeks?) with my server. I
have three WD5000YS (500gb) drives in RAID5, on an Asus A8N
motherboard which is nForce 4. I've even RMA'd one of the drives, but
now I'm thinking the drives are fine.

The drive seems to have issues under heavy to moderate IO. I unmounted
my raid, and forced an e2fsck. e2fsck didn't even print anything out,
I got this.

These errors have been happening on various .22 kernels, and this
message is from the hot-off-the-press .23 kernel. This message is
followed by a hard freeze.

I'm in the process of figuring out why netconsole isn't quite working,
so hopefully I can provide more information soon. The server is
currently frozen, when I get home I can perhaps provide more
information? lspci?

Looks like another rebuild of the array when I get home.


Thanks,
Greg
