Re: What is wrong with kernels 5.X on sparc64 ?
I looked up my old bug postings on Netra240:
https://lkml.org/lkml/2019/11/18/205
https://lore.kernel.org/netdev/6d3e3d29-f23a-dd49-6b4b-f7b6bf7398ab@linux.ee/T/
I now remember that I could not produce a working kernel on Ultra 45 - debian-ports 5.2 kernel worked,
self-compiled 5.3, 5.4-rc4, 5.4-rc8, 5.2 did not work. now 5.6 also did not work.
So I reconnected and started the Ultra 45. It boots up with 5.4 (with warnings in dmesg)
5.6.0 built with gcc-8.3.0 booted up but died during git pull:
