https://bugzilla.suse.com/show_bug.cgi?id=1233416 https://bugzilla.suse.com/show_bug.cgi?id=1233416#c6 --- Comment #6 from Johannes Meixner <jsmeix@suse.com> --- Tim K, to avoid the issue you can disable the CUPS baclend /usr/lib/cups/backend/serial (which is not part of CUPS but of cups-filters) as 'root' either by removing execute permissions # chmod a-x /usr/lib/cups/backend/serial or by deleting the /usr/lib/cups/backend/serial file. Only offhanded guesses: Do you have perhaps some hardware connected via a serial port (also e.g. perhaps via some USB to serial adapter or whatever else)? Is your laptop perhaps connected to a docking station where some serial hardware stuff exists or something like that? I know nothing about serial hardware and/or any software related to serial hardware (including the kernel). For comparison how it looks with openSUSE Leap 15.5 on my homeoffice workstation which is real hardware (I have openSUSE only on a virtual machine) long lines shown wrapped here: -------------------------------------------------------- # dmesg | grep -i serial | grep -v 'SerialNumber' [ 0.980064] Serial: 8250/16550 driver, 32 ports, IRQ sharing enabled [ 0.980255] serial8250: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a 16550A -------------------------------------------------------- # /usr/lib/cups/backend/serial && echo OK serial serial:/dev/ttyS0?baud=115200 "Unknown" "Serial Port #1" OK -------------------------------------------------------- -- You are receiving this mail because: You are the assignee for the bug.
