Hi Martin,
From your diff info, maybe we can analyze this problem step by step.
1、According to your diff info about first eject and first hot add, the pci device 11:00.0 Mass storage
controller was removed and was added ok at pci device level;
2、The main problem is 11:00.0 Mass storage controller can not bind its driver normally, right?
3、According to diff info about first hotadd and coldplug, the mainly diff is
> + Region 0: Memory at f6c84000 (64-bit, non-prefetchable) [disabled] [size=128]
> + Region 2: Memory at f6c80000 (64-bit, non-prefetchable) [disabled] [size=16K]
> + Region 4: I/O ports at c000 [disabled] [size=128]
and
MaxReadReq 4096 bytes ----> MaxReadReq 512 bytes
So maybe we can try to find why the memory range was disabled after hot add.
Martin, can you provide /proc/iomem info when the system bootup, after first eject and
first hot-add?
I suspect the driver release its MMIO successfully after first eject.
Thanks!
Yijing.
