Ok. I have a few suggestions.
Could you capture without truncating the lines? (option -w of minicom
itf it is indeed the culprit). And your configuration as NUMA enabled,
please disable it.
The only thing different between the two logs seems to be the IRQ routing:
working:
[ 2.335156] ahci 0000:00:1f.2: PCI->APIC IRQ transform: INT B -> IRQ
19
not working:
[ 3.614523] ahci 0000:00:1f.2: PCI INT B -> GSI 19 (level, low) ->
IRQ 19
On two core i7 I have access to, one gives PCI-MSI-dege, the other
IO-APIC-fasteoi, none is level. Could you show us the result of
grep ahci /proc/interrupts
in the working and non-working case?
Do you have MSI enabled?
