See https://git-scm.com/docs/git-bisect Jiang, Олег bisected this to 991de2e59090 ("PCI, x86: Implement pcibios_alloc_irq() and pcibios_free_irq()"). Олег, please double-check and confirm that 890e4847587f works and 991de2e59090 fails. Then please add some printks in the pcibios_enable_device() and pcibios_alloc_irq() paths and in your driver to see exactly what changed between 890e4847587f and 991de2e59090 Bjorn > > 23.01.2016 17:54, Bjorn Helgaas пишет: > > >[+cc linux-kernel] > > > > > >Hi Олег, > > > > > >On Sat, Jan 23, 2016 at 1:08 AM, Олег Мороз <oleg.moroz@xxxxxxxxxxxxx> wrote: > > >>Hello.
