Comment 6 for bug 343749

It looks like Jaume Sabater might be correct on his issue in post in #1. The problem he encountered appears to be a MSI problem. Some systems I've seen the past cause issues with adapters and so it must be disabled. Newer versions of the driver have the option to disable MSI (see http://lxr.free-electrons.com/source/drivers/message/fusion/mptbase.c#L96). You should be able to pass these options on boot/install as well (see https://help.ubuntu.com/8.04/installation-guide/i386/boot-parms.html)

Luc Stepniewski in post #2 appears to have a different issue since it only occurs during heavy load. This would suggest to me a problem between fw/driver. An upgrade of one at a time to the latest would help narrow down things. My guess though is that during heavy IO, the card locked up and couldn't be recovered by the driver.

If anyone has the issue where the card can't be initialized during driver load (either boot or by modprobe), you should try loading mptbase by "insmod /lib/modules/..../mptbase.ko mpt_msi_enable_sas=0

thehighhat are you able to reproduce the problem? the 1068E driver should be available in the kernel during boot. For some reason it isn't being detected or loaded. I know for a fact that a generic 1068e chip will load in ubuntu 10.04/10.10 so some logs would be needed. If you can get either dmesg or /var/log/messages from boot, that might help clue us in on the problem.
