Panic on boot of fresh 8.3.0-RC1-x64 USB install with Intel S1200BTL

[pauldoom]

I have been dealing with an annoying issue with 8.3.0-RC1 and previous 8.3.0 pre-releases on my S1200BTL based server. On boot from USB (with a ISO installed system, or with a image DDed directly to USB) I get the following:

Code:

Trying to mount root from ufs:/dev/ufs/FreeNASs1a

This happens with multiple brands of USB stick. 8.2.0 works fine on the same sticks. 8.3.0-RC1 works fine if installed on a standard hard drive or SSD. I have tried various settings in BIOS to no avail. (USB compatibility settings, SATA mode, disabling all MP features and booting single core, etc) This crash only happens with 8.3.0 series installed to USB.

Anyone else seeing this on a S1200BTL? (Just wanted to check before opening a bug report.)

No, you're free to bug report it but I am pretty sure it will be useless. You might get better luck reporting it directly to FreeBSD or searching about it in google.

Oh, I have spent plenty of time with The Goggle on this one.

Fair enough. I will file a report and then try to reproduce with vanilla FreeBSD and report it there as well. Thanks!

I can confirm 8.3.1-RELEASE-x64 boots on S1200BTL successfully when the disk is imaged in another system. I will attempt an installation now.

Verified that I can successfully install from CD to a USB stick in S1200BTL and boot from it afterward.
