Dell BOSS-S1 adapter or HBA330 non-raid

Hi all,

did anyone installed and boot successfully OpenBSD on Dell BOSS-S1
adapter or HBA330 non-raid controller ?
I've got Dell R740xd in lab and of course for storage controllers there
are BOSS-S1 and HBA330. :)
OpenBSD can be installed on these controllers but unfortunately it panic
at boot.

I will send proper bug report to bugs@, but I would like to know if
someone have some experience with this controllers and OpenBSD.

Thank you...
