I released the RC3 of kernel 5.5 for the X1000 and X5000 today.
New:
- PowerPC fixes 5.5-4
- X5000/20 and X5000/40: the mem-v3 patch has been added to the official kernel source code
- Linux Git log
- Phoronix articles, reviews and news stories covering Linux 5.5

Please test the kernels.
Thanks,
Christian
