https://bugzilla.suse.com/show_bug.cgi?id=1167146 https://bugzilla.suse.com/show_bug.cgi?id=1167146#c22 --- Comment #22 from robert spitzenpfeil <rs.opensuse@spitzenpfeil.org> --- I've run some tests with "5.8.7-1-default". So far it looks very good - without disabling LPM myself. There are the usual hiccups with SANE and my old canon scanner, but so far I was _not_ able to the the USB ports / the USB-C adapter stuck. I've removed my rc-local script to disable LPM as per comment 18. It seems LPM is disabled nevertheless, but it wasn't me this time. --- snip --- /sys/devices/pci0000:00/0000:00:1c.6/0000:03:00.0/usb4/4-0:1.0/usb4-port2/usb3_lpm_permit 0 /sys/devices/pci0000:00/0000:00:1c.6/0000:03:00.0/usb4/4-0:1.0/usb4-port1/usb3_lpm_permit 0 /sys/devices/pci0000:00/0000:00:1c.6/0000:03:00.0/usb4/4-1/4-1:1.0/4-1-port4/usb3_lpm_permit 0 /sys/devices/pci0000:00/0000:00:1c.6/0000:03:00.0/usb4/4-1/4-1:1.0/4-1-port2/usb3_lpm_permit 0 /sys/devices/pci0000:00/0000:00:1c.6/0000:03:00.0/usb4/4-1/4-1:1.0/4-1-port3/usb3_lpm_permit 0 /sys/devices/pci0000:00/0000:00:1c.6/0000:03:00.0/usb4/4-1/4-1:1.0/4-1-port1/usb3_lpm_permit 0 /sys/devices/pci0000:00/0000:00:14.0/usb2/power/usb3_hardware_lpm_u2 disabled /sys/devices/pci0000:00/0000:00:14.0/usb2/power/usb3_hardware_lpm_u1 disabled /sys/devices/pci0000:00/0000:00:14.0/usb2/2-0:1.0/usb2-port7/usb3_lpm_permit 0 /sys/devices/pci0000:00/0000:00:14.0/usb2/2-0:1.0/usb2-port5/usb3_lpm_permit 0 /sys/devices/pci0000:00/0000:00:14.0/usb2/2-0:1.0/usb2-port3/usb3_lpm_permit 0 /sys/devices/pci0000:00/0000:00:14.0/usb2/2-0:1.0/usb2-port1/usb3_lpm_permit 0 /sys/devices/pci0000:00/0000:00:14.0/usb2/2-0:1.0/usb2-port8/usb3_lpm_permit 0 /sys/devices/pci0000:00/0000:00:14.0/usb2/2-0:1.0/usb2-port6/usb3_lpm_permit 0 /sys/devices/pci0000:00/0000:00:14.0/usb2/2-0:1.0/usb2-port4/usb3_lpm_permit 0 /sys/devices/pci0000:00/0000:00:14.0/usb2/2-0:1.0/usb2-port2/usb3_lpm_permit 0 --- snip --- There is one line in "dmesg" that might explain this. "usb usb4: We don't know the algorithms for LPM for this host, disabling LPM." This did exist previously (e.g. booting 5.7.7-1-default), but maybe it didn't work as it should have. If this now happens automagically, I'm more than OK with that. I'll report back after some days of using the machine + adapter without explicitly disabling LPM myself and if it keeps on working I vote for closing this bug. -- You are receiving this mail because: You are the assignee for the bug.
