Subject: HT1000 SATA broken by "x86, irq, ACPI: Use common irqdomain map
interface to program IOAPIC pins"
Hi
The patch d7b830013f59cf586c1cec3caa1ce7156da59a13, committed to 3.17-rc1,
breaks the SATA controller (sata_svw driver) on HT1000 ServerWorks
chipset. The other drivers work correctly.
With the patch d7b830013f59cf586c1cec3caa1ce7156da59a13, the SATA
controller times out after every command with lost interrupt.
With the patch 16ee7b3dcc56be14b9a813612cff2cc2339cdced, the SATA driver
can't be loaded at all, it fails with:
sata_svw 0000:01:0e.0: version 2.3
Failed to set pin attr for GSI11
sata_svw 0000:01:0e.0: PCI INT A: failed to register GSI
sata_svw: probe of 0000:01:0e.0 failed with error -1
