As far as I know, I have not come across any issues while upgrading the bios for this board.
Yes, there is one thing that i used to do after upgrading the bios on my board.
Before allowing the OS to boot from the hard drive configuration, i went into the bios by pressingf F2 and made sure that my sata port are configured as raid.
Advanced >> Drive Configuration >> Configure SATA as RAID.
Save and Exit.
The reason for this is because after a bios update, the new bios is set as to default configuration, hence the sata ports are configured as IDE.
Anyway, you can give it a try if you want. I would always make sure that i do have a back up for my precious data.
Here is the latest bios release notes where you can see the fixes
All the best,
