I sent a patch that I would like you to test. It adds some additional
sanity checking to the block limits handling. Given the VPD output you
sent earlier, I am hoping it will work around the issue.
I still can't explain how the physical block size can be unset given
that it is reported by the device and the capacity is > 0xffffffff. I
even tried to tweak scsi_debug to see if somehow the no_read_capacity_16
flag for card readers happened to be set in your case and caused us to
go down the wrong path. But no. I'm stumped.
Do you have any READ CAPACITY errors or messages in your log? There were
none in the output you sent.
Currently compiling...
# dmesg | grep -i capacity
... returns empty. Are there other tests I should run?
Meanwhile, this is everything dmesg gives me when plugging in the drive,
running lsblk and launching gparted:
# dmesg -wH
