Hi,

this one causes kexec to hang.

Can you give more info about the hang, like the log? Is patch
synchronize-device-shutdown.patch applied? kexec takes the same way
to shutdown device, so does shutdown work in the system?

Thanks,

Ah, I though it silently hangs, but no, I had forgotten to switch a
logging console. There is nobody-cared interrupt 19 followed by plenty
of sata ports resets. The same happens on reboot.

According to /proc/interrupts, irq 19 is usb specific:
 19:          0          0   IO-APIC-fasteoi   ehci_hcd:usb1, uhci_hcd:usb7

But ahci enables the legacy one at 19 too:
ahci 0000:00:1f.2: version 3.0
  alloc irq_desc for 19 on cpu 0 node 0
  alloc kstat_irqs on cpu 0 node 0
ahci 0000:00:1f.2: PCI INT B -> GSI 19 (level, low) -> IRQ 19
  alloc irq_desc for 27 on cpu 0 node 0
  alloc kstat_irqs on cpu 0 node 0
ahci 0000:00:1f.2: irq 27 for MSI/MSI-X
ahci 0000:00:1f.2: AHCI 0001.0200 32 slots 6 ports ? Gbps 0x3f impl SATA
mode
ahci 0000:00:1f.2: flags: 64bit ncq sntf pm led clo pmp pio slum part ems
ahci 0000:00:1f.2: setting latency timer to 64


Is this that ahci frees msi and interrupts at all at the shutdown stage
and you "schedule" and wait for an interrupt afterwards? (And then the
interrupt comes, but usb says: no, it's not mine.)

ok, maybe there is ordering issue, sd shutdown is after ahci shutdown, we can't
simplifily make sd sync shutdown. Thanks for pointing out the patch is broken.

Thanks,
