As such there is no stack dumped on the console during crash. System restarts from the FreeBSD boot prompt without any message on the console. Still I have a picture where monitor goes off during data load. PFA(sorry for the flash) Ugh. I don't have a good suggestion on debugging this besides adding printfs to the EFI loader code and/or moving an infinite loop around in the code to narrow down exactly when it resets. It is quite possibly specific to the EFI firmware on your machine (at least, reproducing the issue might be). > Regards/Murthy Bhat > > -----Original Message----- > From: John Baldwin [mailto:jhb@freebsd.org] > Sent: Monday, August 29, 2016 10:52 PM > To: freebsd-current@freebsd.org > Cc: Murthy Bhat ; FreeBSD-current@FreeBSD.org > Subject: Re: FreeBSD 11.0-RC1 boot prompt kernel load issue. > > EXTERNAL EMAIL > > > On Wednesday, August 24, 2016 01:35:08 PM Murthy Bhat wrote: > > > > Hi, > > > > This is regarding issue faced during OS(FreeBSD 11.0-RC1) installation on the storage behind our smartpqi storage controller. > > Are you using EFI or legacy boot? Also, can you capture a screenshot of the crash messages? If it is not EFI, we probably crashed in the BIOS routines used to read data from the USB drive. It may be a BIOS bug (which isn't easily fixable), but we would need the register dump from the crash to figure anything out. > > -- > John Baldwin -- John Baldwin
