Can't Update ICX7150-C12P to 09.0.10

[GreensTheorem]

Hey,

I've got an ICX7150-C12P running SPR08095m.bin (UFI)

When I try to upgrade to 09.0.10 via

copy tftp flash 192.168.129.30 ICX7150/SPR09010dufi.bin primary
...lots of output, but no errors
copy tftp flash 192.168.129.30 ICX7150/SPR09010dufi.bin secondary
...lots of output, but no errors
boot system flash primary

I get

Extract UFI FI version success, version = SPR09010d.bin

And after another reboot, the switch is stuck in a (re)bootloop

Is this a known issue? Sadly I don't have a support contract (I would like to buy one though, but you're not selling it to me).

Any ideas? I have been able to reproduce this error multiple times (recover to 08.0.90mc -> Upgrade to 08.0.95m -> Works -> Upgrade to 09.0.10 -> Failure)

I have tried multiple versions of 09.0.10, like 09.0.10d, 09.0.10h or 09.0.10j
