I have a system that stopped booting Linux between kernel versions 4.4.9
and 4.5.3. It has a SATA + NVMe accelerated volume that I use with
Windows and a separate SATA drive with my Linux installation. I'm not
expecting the remapped NVMe thing to be accessible, just the Linux disk,
but none of the drives are accessible.
Bisecting the changes turned up d684a90 as the first failing change.
Passing pci=nomsi also allows the system to boot newer kernels. Just to
be sure, I built a recent kernel (4.12.9) with the PCI_IRQ_MSIX flag
removed from the per-port call to pci_alloc_irq_vectors in
ahci_init_msi. This also allowed the system to boot normally.
I'm totally out of my depth though so I'd really appreciate it if anyone
has some ideas on how to proceed with a proper fix.
Thanks,
John
