yes I have it all. While preparing the the requested info I could further nail down the issue. It seems to depend on type of boot. In Legacy/BIOS boot the problem shows with 4.4.66, see below. When the same Leap install is booted in an EFI boot it does not, see further below. I have 2 disks in my Laptop, one where TW sits, this is set up as BIOS boot disk. The other where Leap 42.3 is installed has an EFI boot partition. When the boot loader is build on either install I always include foreign OS, so alternate boots are easy, but one way EFI and the other BIOS. I need some more time to boot all three variants in EFI and in BIOS mode to find out whether it is really a kernel version issue or a boot mode one. Will add another comment here then. Hope this first set of information is a starting point for you anyhow --- MemTotal: 17353432 kB MemFree: 16090380 kB MemAvailable: 16398808 kB Buffers: 55732 kB Cached: 507548 kB SwapCached: 0 kB Active: 707284 kB Inactive: 322276 kB Active(anon): 467580 kB Inactive(anon): 7936 kB Active(file): 239704 kB Inactive(file): 314340 kB Unevictable: 32 kB Mlocked: 32 kB SwapTotal: 67087036 kB SwapFree: 67087036 kB Dirty: 8 kB Writeback: 0 kB AnonPages: 466304 kB Mapped: 277128 kB Shmem: 9244 kB Slab: 80488 kB SReclaimable: 38652 kB SUnreclaim: 41836 kB KernelStack: 6672 kB PageTables: 29052 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 75763752 kB Committed_AS: 2071892 kB VmallocTotal: 34359738367 kB VmallocUsed: 0 kB VmallocChunk: 0 kB HardwareCorrupted: 0 kB AnonHugePages: 145408 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB DirectMap4k: 129216 kB DirectMap2M: 3956736 kB DirectMap1G: 14680064 kB Linux version 4.4.66-2.g00cfa4c-default (geeko@buildhost) (gcc version 4.8.5 (SUSE Linux) ) #1 SMP Sat May 6 05:11:09 UTC 2017 (00cfa4c) ---- reboot into same kernel 4.4.66-2 on Leap 42.3 in an EFI boot - issue can not be found.
