Booting FreeBSD11.1-RELENG from a USB stick, loader works fine keyboard

screenshot.  Tried safe mode same occurrence.

CDROM is via a USB, so that's a no go and I've not had luck booting
UEFI
iSCSI nor PXE yet, so I'm stuck without a keyboard (no PS/2 connectors)
or
essentially any boot media.

For reference Xen 7.2 is running fine so at first blush it's not faulty
hardware.
USB3 mode on and off (ie force USB2) in the BIOS makes no difference.
All Firmwares current.

Any suggestions on how to move forward with this?  I tried turning on
verbose mode, but I'm not sure how to capture that nor where to look.


Hi,

USB_ERR_TIMEOUT might be an indication of a PCI IRQ issue.


Try to set:

hw.usb.xhci.use_polling=1

from the loader as a temporary quirk. Then try to dump information about
IRQ's like "vmstat -i" "dmesg" and so on.

--HPS

Thanks Hans, but unfortunately that made no difference.  Here's my full

loader.conf

vfs.mountroot.timeout="10"
boot_multicons="YES"
boot_serial="YES"
comconsole_speed="115200"
console="comconsole,efi"
kern.cam.boot_delay="10000"
hw.usb.xhci.use_polling=1


Did you enable USB 3.0 in the BIOS when trying this?

--HPS

It was configured with USB3.0 OFF
I just toggled it ON, same result.

I verified the sysctl polling value from the loader before booting

Hi,

I suggest you bring this issue up with Dell customer support.

Further, maybe Linux XHCI / EHCI has a quirk for Dell R630.

Alternativly you can try to debug the XHCI/EHCI debug prints on your own. If you get a timeout it means something is not communicating like expected in the XHCI/EHCI DMA descriptors.

--HPS
