@randyh62 Here is the output of `xbutil examine` with some OS details. It also shows the problem I'm facing. I described it in my [support forum post](https://support.xilinx.com/s/question/0D52E00006uVLA2SAO/u55n-flashing-the-shell-partition-doesnt-work?language=en_US&t=1640880209936) ``` $ sudo...

@randyh62 Can you please give me a download link for xrt 2.12.456 as in your system. Unfortunately xrt 2.11.634 fails to build the DKMS drivers on Ubuntu 20.04, kernel 5.11.

I downgraded the kernel to 5.8.0-63 and that allowed the 2.11.634 DKMS drivers to be built. Also the `sw_emu` example target built OK. The `hw_emu` target fails with ``` terminate...

Oh, even though xrt built the DKMS modules, the `xclmgmt` module is useless. ``` modprobe: ERROR: could not insert 'xclmgmt': Unknown symbol in module, or unknown parameter (see dmesg) ```...

The same DMA error blocks execution of [Vitis tutorial examples](https://github.com/vkomenda/Vitis-Tutorials/tree/u55n-getting-started/Hardware_Acceleration/Introduction). Which effectively makes XRT useless (on kernel 5.15). Can you maybe suggest how to debug this? **Edit** Tested on kernel...

This issue arises in the current master. Same output on 5.10, 5.11, 5.15. The latter requires a patch #6092 for kernels 5.14+. It's possibly a regression because 2.12.427 works fine.

@afck, this is a great optimisation. Those _N - 2 f_ full `Echo`s should be valid leaf values in order for `decode_from_shards` to compute a value. We won't have any...

Do you mean if there are more than _f_ rather than _g_ faulty nodes?
