It looks like a window that is moving and I think is sometimes called a Microsoft key and might be called the meta key in Linux. I have that key on both sides of my keyboard space bar. I have another key only on the right side between the Ctrl and the flying window key that looks like a document with a mouse pointer on it. What are these keys called nowadays? Is one of those the super key you mention? What is that key with the mouse pointer on it called? I don't recall ever using that key for anything. Don't know if it does anything either but it might.

Thanks, -- Valmor I think the error messages you're getting indicate inability to access your rootfs. Have you perhaps changed the fs drivers in the latest kernels, from built in to modules? Have you diff'ed your 6.1.41-gentoo .config file against the latest kernels' .config files to see what might have changed/missing? You can set up a netconsole to check boot time messages: https://www.kernel.org/doc/Documentation/networking/netconsole.txt https://wiki.ubuntu.com/Kernel/Netconsole In summary, build netconsole in the new kernel, or as a module, change GRUB's default CMDLINE from "quiet splash" to "debug" and add netconsole in the kernel command line: netconsole=@/,[PORT]@[DEST_IP] Then at the destination PC launch netcat/socat/telnet; e.g. nc -u -l -p [PORT] and reboot the PC you want to debug with the latest kernel, while watching the output on the destination PC's terminal with nc. Here is the diff for the config files: -> diff config /boot/config-6.1.41-gentoo 3c3 < # Linux/x86 6.1.53-gentoo-r1 Kernel Configuration --- > # Linux/x86 6.1.41-gentoo Kernel Configuration 5c5 < CONFIG_CC_VERSION_TEXT="gcc (Gentoo 13.2.1_p20230826 p7) 13.2.1 20230826" --- > CONFIG_CC_VERSION_TEXT="gcc (Gentoo 12.3.1_p20230526 p2) 12.3.1 20230526" 7c7 < CONFIG_GCC_VERSION=130201 --- > CONFIG_GCC_VERSION=120301 455d454 < CONFIG_CPU_SRSO=y 457d455 < # CONFIG_GDS_FORCE_MITIGATION is not set 646d643 < CONFIG_ARCH_HAS_CPU_FINALIZE_INIT=y 3136d3132 < CONFIG_VIDEO_V4L2_SUBDEV_API=y 3139,3140d3134 < CONFIG_V4L2_FWNODE=m < CONFIG_V4L2_ASYNC=m 3236c3230,3233 < CONFIG_VIDEO_CAMERA_SENSOR=y --- > > # > # Camera sensor devices > # 3295a3293 > # end of Camera sensor devices I guess I could explore some of this difference.

I can't see anything fishy in fstab, no network-mounts that might have failed. From the original message it looks like your network interface is not being set up correctly, but you should still be able to boot. Also "rmdir: command not found" probably means your PATH does not get set, or else you don't have execute permissions on rmdir. Odd that this should be dependent on kernel version. You should go over and verify that the transfer of your linux .config went OK. Then verify that the new config does in fact enable modules for your network card, and enable the necessary settings for your init system (looks like you are using openrc?)

I mounted using your options and this is a decent improvement. I'm not sure which option makes it faster but it is faster, almost double. A few examples using fairly large file sizes for good results. 3,519,790,127 100% 51.46MB/s 0:01:05 3,519,632,300 100% 51.97MB/s 0:01:04 3,518,456,042 100% 51.20MB/s 0:01:05 It may not look like much, still slower than just a straight copy with no encryption, but given previous speeds, this is a nice improvement. I think before I was getting about 25 to 30MB/s before. This is the settings shown by the mount command now, which should be what it is using. root@fireball / # mount | grep TV 10.0.0.7:/mnt/backup on /mnt/TV_Backup type nfs4 (rw,relatime,vers=4.0,rsize=1048576,wsize=1048576,namlen=255,hard,nocto,proto=tcp,nconnect=4,timeo=600,retrans=2,sec=sys,clientaddr=10.0.0.4,local_lock=none,addr=10.0.0.7) root@fireball / # I think it took all your options and is using them. If you have ideas that would speed things up more, I'm open to it but this is a nice improvement. I still think the encryption slows things down some, especially on the NAS end which is much older machine and is likely fairly CPU intensive. A newer CPU that has the same clock speed and number of cores would likely do much better, newer instruction support and all. I think I read somewhere that newer CPUs have extra stuff to speed encryption up. I might be wrong on that. Thanks much. Any additional ideas are welcome, from anyone who has them. If it matters, both rigs are on UPSs. Dale :-) :-) P. S. Those who know I garden, my turnip and mustard greens are popping up. My kale and collards are not up yet. I watered them again to help them pop up. Kinda dry here and no rain until the end of the next week, they think. They never really know what the weather is going to do anyway.
