Hello all,

After upgrading to the below release of skarnet packages, my system
is not booting anymore on MIPS. I am using buildroot and the s6-linux-init-skeleton
provided there by Éric Le Bihan.

The init usually stays blocked there:

  s6-rc: info: processing service fdholder: starting

with the following processes running:

  136 root s6-rc -v 3 -u change services-all
  143 root s6-fdholderd -1 -i data/rules
  146 root s6-ipcserverd -1 -- s6-ipcserver-access -v0 -E -l0 -i data/rules -- s6-sudod -t 2000 -- /usr/libexec/s6-rc-oneshot-run -l
  173 root s6-svlisten1 -u -- /run/s6-rc/scandir/klogd-log s6-svc -u -- /run/s6-rc/scandir/klogd-log
  183 root s6-ftrigrd
  296 root s6-svlisten1 -U -- /run/s6-rc/scandir/fdholder s6-svc -u -- /run/s6-rc/scandir/fdholder
  297 root s6-ftrigrd

and I regularly see the following message, even though not consistently:

  s6-ftrigrd: fatal: unable to flush asyncout: Broken pipe

When I build the very same system for x86 I do not see any issue, it is very stable, so I
suspect a cross-compilation issue. Since buildroot patches skalibs in order to determine
system capabilities through build-time asserts instead of runtime tests, it is possible that
something goes wrong there. However I have adapted the patches to the new release,
and so far I cannot identify any error in the detected system settings.

If anyone has any idea to help the investigation, it would be highly appreciated :).
Maybe for example a hint on what could cause s6-ftrigrd to get a broken pipe ?

Kr,
Lionel

By the way, I have upgraded, without control, I see it is working well
and fine on a reboot.
