Default Karmic disk/raid troubles

I am running Karmic on a Supermicro server with 7 KVM guests on it.

The disks are split on 2 raids :

4 disks in RAID 6* - boot and kvm storage
2 disks in RAID 1 - backup

From a month or so i started getting hangs on the server. Disk I/O failures, the server becomes unresponsive, i cannot even connect to the monitor through the IPMI KVM over LAN .

I have a similar server on another location ( though a newer hwarid card , but again LSI ) that doesn't have those problems.

I have managed to reproduce the bug today, by issuing a kvm-img convert command from qcow2 to raw format ( 15G image ).* All guests were shut off at that time.

Since i have first encountered this problem i have reinstalled the server with a clean karmic install.* Same thing happens. Here are some logs :

When the above appears in the logs, all disk i/o stops and i cannot launch anything ( htop, dstat, iotop, aptitude do not start at all ).
I can however do cat /proc/loadavg and i see an increasing load on the system ( last time it went up to 10 before the logs below started )

Any ideas ? The LSI controller doesn't log any errors in his event log. The disk come up clean, and i have even ran a consistency check on both raid arrays.

Is there any known problem with the specific raid controller. I could try replacing it with the model that i have on the other server and where i don't see that problem.

The disks are split on 2 raids :

4 disks in RAID 6 - boot and kvm storage
2 disks in RAID 1 - backup

From a month or so i started getting hangs on the server. Disk I/O failures, the server becomes unresponsive, i cannot even connect to the monitor through the IPMI KVM over LAN .

I have a similar server on another location ( though a newer hwarid card , but again LSI ) that doesn't have those problems.

I have managed to reproduce the bug today, by issuing a kvm-img convert command from qcow2 to raw format ( 15G image ). All guests were shut off at that time.

Since i have first encountered this problem i have reinstalled the server with a clean karmic install. Same thing happens. Here are some logs :

When the above appears in the logs, all disk i/o stops and i cannot launch anything ( htop, dstat, iotop, aptitude do not start at all ).
I can however do cat /proc/loadavg and i see an increasing load on the system ( last time it went up to 10 before the logs below started )

Any ideas ? The LSI controller doesn't log any errors in his event log. The disk come up clean, and i have even ran a consistency check on both raid arrays.

Is there any known problem with the specific raid controller. I could try replacing it with the model that i have on the other server and where i don't see that problem.
