Hello Bjorn,
I will enable CONFIG_PCIEASPM and CONFIG_PCIEASPM_DEFAULT for the RC5
of kernel 6.18 and test it with the X1000.
Thanks,

Hello Bjorn,
I tested the RC5 of kernel 6.18 with CONFIG_PCIEASPM and
CONFIG_PCIEASPM_DEFAULT enabled on my X1000 today. Unfortunately the
boot problems are still present.
Cheers,
Christian
