dsd: this one is for you. slepnoga: what USB device was this? I can't reproduce on any of my USB hardware.
Created attachment 271897 [details] kernel error My apologies for my haste. I checked the kernel logs and found problems in the module ext2, who worked through the usb drive. Directly to the problem is incorrectly input to lsub, even though I was hoping that verify the input data - ABC programming:) if you feel it necessary to close the bug, do it.
