"use new doorbell-bit-5 reset method" failed to reset the controller

Hi Stephen,

With linux the latest kernel, when do kdump test on HP DL585G7 we found it failed to reset the controller, driver complained "'Bit 2 doorbell reset' is supported, but not 'bit 5 doorbell reset', Firmware update is recommended", we have upgraded the firmware to the latest but kdump kernel still failed with the message.

After revert commit cf0b08d0cd87ada9d284925834d08fb8026da888, kdump work fine.

Seems doorbell-bit-5 reset method did not work properly with the device? Any input will appreciate.

What firmware revision do you have?

I think you need 5.06, which just came out on June 24.
