https://bugzilla.kernel.org/show_bug.cgi?id=213081 --- Comment #13 from Peter Ganzhorn (peter.ganzhorn@xxxxxxxxxxxxxx) --- I tried to revert the commit on 5.12. Checking out 674f8438c121 and then reverting worked as you suggested, thanks for the hint. Results: 1) Kernel built at / with commit 674f8438c121 stops at the following output: ... usb-storage 6-2.3.1:1.0: USB Mass Storage device detected scsi host6: usb-storage 6-2.3.1:1.0 scsi 6:0:0:0: Direct-Access Generic STORAGE DEVICE 1531 PQ: 0 ANSI: 6 sd 6:0:0:0: Attached scsi generic sg2 type 0 Which is clearly related to my card reader. After that, the boot process DOES NOT CONTINUE. 2) Kernel without commit 674f8438c121: Boots just fine and my card reader works. Seems like the commit git bisect found makes things a lot worse indeed. I guess there were other changes involved since 5.12 at least continued to boot with the device attached. What else could I do to help you investigating this? -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
