Probably some tool did something weird:

^^^^^^^^^^^

% cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: Samsung Model: Portable SSD T5 Rev: 0
Type: Direct-Access ANSI SCSI revision: 06
and as far as I can reconstruct the oops correlated with attaching that
drive via USB. But attaching the drive again, does not reproduce it.

Maybe, right after the part of the log in my mail before I see
note: colord-sane[13243] exited with irqs disabled
note: colord-sane[13243] exited with preempt_count
usbcore: registered new interface driver usb-storage
scsi host0: uas
usbcore: registered new interface driver uas
scsi 0:0:0:0: Direct-Access Samsung Portable SSD T5 0 PQ: 0 ANSI: 6
