I had ATTO SAS modules (ExpressSAS Adapters) running on Ubuntu 10.4 for two years now. Upgraded to 12.4 and now there are issues. There is a known conflict between the ATTO SAS driver and the PM8001 driver. Here's what I did to work around it. I'd like to compare notes...
1) I disabled the ATTO driver in the BIOS via a setting in the ATTO card NVRAM. Now the BIOS doesn't hang.
2) The ATTO driver installer renames the pm8001.ko driver to pm8001.bkup. A cheap way to black list it - however even with the pm8001 driver removed, after boot-up the driver is still loaded. How it got there I don't know.
3) After booting I can 'rmmod pm8001' then 'insmod esas2hba' then I'm in business.
There must be a better solution. Is grub loading the pm8001 driver? Every three or four boots the boot-up hangs with a blank pink/orange Ubuntu screen. Looks like something bad is happening in grub.
Anyone dealing with this?
thx, Jack.
