That's good to know any explains why I cannot reproduce as I don't have
an UEFI system to test with.
I suspect something the UEFI BIOS does that upsets the Linux USB gadget
stack.
I could debug this if I had access to a system, either physically here
or remotely, where I can remotely install/netboot BMC kernels (so I
would probably need a serial connection to the BMC and a PDU), any
suggestion on how to do that ?
Otherwise, would there be a way to reproduce that with the x86 running
in qemu ? (plugging the AST2500 eval board USB into the host and
passing it through for example) ?
Cheers,
Ben.
