No joy. The Toshiba SSD only has Windows/GUI firmware update tools.
Relative to n271055, I have reduced the necessary patch for my hardware to boot
to be:
06:41:08 /usr/src# git diff

- gone = bus_child_present(dev) == 0 ||
- (nvme_mmio_read_4(ctrlr, csts) == NVME_GONE);
+ gone = (nvme_mmio_read_4(ctrlr, csts) == NVME_GONE);
if (gone)
nvme_ctrlr_fail(ctrlr);
else
I'm trying to look into why my hardware results in returning
(bus_child_present(dev) == 0) but I'm not finding where the *definition* of
BUS_CHILD_PRESENT is. Plenty of references, but no definition, to my novice
eyes.
Clues appreciated, as always.
