(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? -- Gilles.
