IPMI screenshot showing problem

The FreeBSD 10.2 and later, including 10.3-REL and 11.0-REL on both i386 and amd64 can not be loaded or installed on all Supermicro X9 motherboards (tested on X9DLR,  X9DBi, X9SCa, X9SCi-LN4F and many others) using IPMI emulated CDROM.

after kernel loaded it stucks on umass1-device probe:

umass1: 8087i (ATAPI) over Blulk-Only; quirks = 0xc101
umass1:8:1: Attached to scbus0

we have digged deeply into the problem and found that it is related to how BSD deals with CDROM cache. Using the best of our knowledge we found a way to fix it:

on the boot time escaping to loader prompt (press 3 in when loader menu appears), and entering following command:

set hw.usb.quirk.0="0x0ea0 0x2222 0 0xffff UQ_MSC_NO_SYNC_CACHE"
boot

after this kernel loads successfully and FreeBSD can be installed without any troubles.

The problem appears only on FreeBSD 10.2 and later. Version 10.1 and previous including but not limited to : 10.0 , 9.3 , 8.4 , 7.4 and 6.4 have no such problem.

Please add this fix to the further releases including 10.4 , as at the moment its barely impossible to install or repair OS on the servers with mentioned motherboards which are very popular.

Thanks,
