Hi Sreekanth, I have bisected the issue down to commit "x86/MSI: Use hierarchical irqdomains to manage MSI interrupts". The timeout happens reliably after two warm boots

Hello, I don't know what's the correct procedure, whether I should file a bug or first report this issue on the kernel mailing-list. So please feel free to tell me to open a ticket in the bugtracker (bugzilla.kernel.org?). But first let me present the issue I encounter: Kernels >= 4.2 (4.2.1
