#18244: procd/init cause reboot loop if kmodloader /etc/modules-boot.d takes to
long
--------------------------+-----------------------------------
Reporter: jj+openwrt@… | Owner: developers
Type: defect | Status: new
Priority: normal | Milestone:
Component: base system | Version: Barrier Breaker 14.07
Keywords: |
--------------------------+-----------------------------------
/sbin/init currently does AFAIK the following (shortened, some steps left
out):
1st watchdog_init()
2nd pid = fork(), for kmodloader /etc/modules-boot.d/
3rd waitpid(pid, NULL, 0) for pid in 2nd
4th preinit()
When the waitpid() does not return in time, the watchdog will trigger and
reset the device.
This might happen on devices with a larger amount of modules in /etc
/modules-boot.d/ and/or slow boot devices for example with software SPI.
The process of kmodloader takes longer as it scans as many modules it
needs to satisfy all dependencies.
It's happening on my TP-W8970, when adding some modules like for more
filesystems or other USB hardware to the base image.
