Hi! I am trying to enable MSI-X, then disable and enable MSI. This fails. ~>modprobe ib_mthca msi_x=1 ~>rmmod ib_mthca
Works fine ~>modprobe ib_mthca msi=1 The second modprobe fails to get interrupts from the device. An attempt to fall back to regular interrupts fails as well: ib_mthca 0000:04:00.0: NOP command failed to generate interrupt (IRQ 201), aborting. ib_mthca 0000:04:00.0: Try again with MSI/MSI-X disabled. ib_mthca 0000:04:00.0: Clearing mask 00000000001f43fe for eqn 2 ib_mthca 0000:04:00.0: Clearing mask 0000000000000400 for eqn 3 ACPI: PCI interrupt for device 0000:04:00.0 disabled ib_mthca: probe of 0000:04:00.0 failed with error -16 Looks like a linux bug, does it not? -- Michael S.
