If a PCI error is detected that cannot be recovered from, there
will be a double call of lpfc_pci_remove_one(), with the second call
resulting in a null-pointer

Currently scsi_wait_scan is only built modular if SCSI is modular.
However, it's perfectly possible for a built in SCSI still to have
modular drivers and thus need scsi_wait_scan as a module. Therefore,
scsi_wait_scan should always be built as a module (unless the kernel
doesn't support modules).

Aha, I'll track it.
And this is a direct command submission path: it already passed both

adding a third won't fix this.
Yeah, I have notice that, however, from the logs, the

I cannot confirm if it have fixed in latest kernel, the server is a
production system, it's hard to debug it and try reproduce.

Hi All,
Any one og you have any idea on scsi inquiry command ?
I want to send an Inquiry command to a scsi device through sd path (.i.e.
