Reproduced with b0eda49bc9b0 ("Merge tag 'u-boot-at91-fixes-2023.04-a' 
of https://source.denx.de/u-boot/custodians/u-boot-at91") and Icy Box 
IB-3804-C31 (same design as IB-3805/IB-3810 but just a single 4 port 
USB3 hub + 4 independent asmedia usb3 to sata converters).

The usb2sata bridges can powered off individually. u-boot crashes with 
just a single bridge with HDD powered on. Works if all bridges are off 
or don't have a HDD connected.

The bridge reports under linux as

Bus 005 Device 003: ID 174c:55aa ASMedia Technology Inc. ASM1051E SATA 6Gb/s bridge, ASM1053E SATA 6Gb/s bridge, ASM1153 SATA 3Gb/s bridge, ASM1153E SATA 6Gb/s bridge
