Hi, I have a RPi 3B running Leap 15.5. I have recently replaced the failing SD card about three weeks ago and all was well. After a zypper patch + reboot cycle it failed to connect to the network. Connecting via a serial cable shows that it hangs at 'Reached basic system'. The early boot messages don't tell me that much, there seem to be some errors, pasted at the end of the message. I mounted the SD card in another machine, looks to mount just fine NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS sda 8:0 1 59.4G 0 disk ├─sda1 8:1 1 64M 0 part /run/media/robert/EFI ├─sda2 8:2 1 500M 0 part └─sda3 8:3 1 6.8G 0 part /run/media/robert/ROOT dmesg complains about 'not properly unmounted', but that should not be a big issue [229713.544212] scsi 0:0:0:0: Direct-Access Generic STORAGE DEVICE 1402 PQ: 0 ANSI: 6 [229713.544584] sd 0:0:0:0: Attached scsi generic sg0 type 0 [229713.788123] sd 0:0:0:0: [sda] 124669952 512-byte logical blocks: (63.8 GB/59.4 GiB) [229713.789352] sd 0:0:0:0: [sda] Write Protect is off [229713.789357] sd 0:0:0:0: [sda] Mode Sense: 21 00 00 00 [229713.790605] sd 0:0:0:0: [sda] Write cache: disabled, read cache: enabled, doesn't support DPO or FUA [229713.800319] sda: sda1 sda2 sda3 [229713.800711] sd 0:0:0:0: [sda] Attached SCSI removable disk [229714.844629] FAT-fs (sda1): Volume was not properly unmounted.
