Nokia N900: usb networking has random delays, random fails

    • Closed Imported Issue created by Administrator @root

    Created by: pavelmachek

    In older versions of pmOS, usb networking on N900 worked reliably if the cable was plugged after the boot. In current pmOS, there are random delays (more then 10 seconds?) and then it usually fails altogether.

    @craftyguy Do you see it, too?

    To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information

      (See also: pmbootstrap#213)

      This could either be a regression in the kernel, or in our initramfs scripts (do you use them?).

      • Could you boot your known working kernel (e.g. kernel.org:pub/scm/linux/kernel/git/pavel/linux-n900.git bt-v4.13) together with the postmarketOS initramfs and see if you can reproduce the issue?
      • If you can not reproduce it, I would try to upgrade the kernel to the latest stable (just change the pkgver in aports/main/linux-postmarketos-stable/APKBUILD to 4.14.15) and test again
      • If that does not help either, then probably only bisecting the kernel helps.

      NOTE: Yes, we have outdated kernels in the repository right now. When we can reliably remove old packages (when #1166 (closed) is reviewed and merged), I'd like to look into setting up a (manual) process to upgrade the kernels and other packages as soon as there is a new release.

      I probably use postmarketos initramfs (prepare MMC image, boot it). I see some problems in new, self-compiled kernels, too.

      Is there easy way to switch to old kernel version in pmos? Kernel that was in pmos at Oct 11 2017 should be working ok.

      Hmm. Switching kernel to old version number in APKBUILD is not enough to get the old kernel version. Let me try reverting:

      then ./pmbootstrap.py build linux-postmarketos-stable --force should do what I want...

      The thing is, when the binary repository has a newer version of the same package name, pmbootstrap will take that one. To use an older kernel, you could do one of the following:

      • Change the pkgver of the kernel you want to use in the aports folder to 9999 (make sure to delete the package if you don't want to use it anymore out of your packages folder: ~/.local/var/pmbootstrap/packages/armhf/ as root, then run pmbootstrap index. Shortcut for deleting all self-compiled packages: pmbootstrap zap -p)
      • Compile it outside of pmbootstrap
      • Run pmbootstrap --mirror-pmOS="" to make it ignore the binary repo. That is then for all packages though, so all of them will be compiled locally (cross-compiler etc.)

      perhaps close this, since it seems a dupe of #99 (closed)
