Hi Anders, I really appreciate your debug data, thanks a bunch for buying the PS2 adapter, very useful. So, seems you are observing an issue with the SATA controller. Could you collect a dmesg from the kdump environment, in this minimal "(initramfs)" shell?
Also, thanks for the previous data - I found an interesting difference between the content of initrds, the regular one has a dkms zfs module, whereas the kdump has the packaged zfs modules. But seems this is not what causing trouble to you, although is interesting to understand why... Let me know if you can collect the dmesg in the kdump failed boot, that'd be really helpful, it might be a kernel bug in the end. And finally, disregards my suggestion (c), thanks for observing that the memory amount reserved is enough, good point.
