Hello, I am facing an issue where I am facing a SAS card Highpoint RocketRaid 2722. I am running the latest driver and firmware. I had an issue with a portable hard drive that wont go beyond unlocking (WD Unlocker). I updated its firmware (which didnt help and i thrown it in garbage.). After the firmware update I have not been able to load windows. It gives be a BSOD with IRQL_NOT_LESS_OR_EQUAL 272x_1x.sys
All used to work well before this step using the WD firmware update utility. I tried system restore, with no avail. Only option I do now is to shut down the DAS and I can boot normally. As soon as I power it on the system crashes and I get the same error as I mentioned before.
I read there: http://windows7themes.net/en-us/5-ways-to-fix-irql-not-less-or-equal/?EsetProtoscanCtx=712a48
that the IRQ if shared with audio bus and raid controller it probably would cause this issue. I have no clue on how to let them use different IRQs. I ran msinfo and i verified this is true. I updated everything, the audio driver, MB chipset, GPU driver and still the same issue. I uninstalled the SAS raid controller with all its files from the system and added it again using the latest driver, still.
Its worthy to mention that I have another internal SATA RAID card installed from the same manafacturer: Highpoint RocketRAID 2320. This one is working with no issues. When I try to uninstall it, and check the delete driver files, and reboot I find it there again using the latest driver. Same when disabling it and restart, It becomes enabled again.
I got a dual boot with Windows 10 Professional x64 and Windows Server 2012. I do not face this issue with Windows Server 2012.
