>Synopsis: serial console no output
>Category: amd64
>Environment:
System : OpenBSD 6.9
Details : OpenBSD 6.9-current (GENERIC.MP) #381: Fri Jul 30
09:02:53 CEST 2021
[email protected]:/home/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
The serial console on this machine stops printing somewhere around the
time /etc/rc is executed. Last line of output on the console:
Automatic boot i
The `sh /etc/rc' process does not exit causing init(8) to wait
indefinitely for it. The same process is stuck here:
#0 ttywait_nsec+0x10e
#1 killjobc+0x86
#2 exit1+0x22a
#3 sys_exit+0x16
#4 syscall+0x3b9
#5 Xsyscall+0x128
I would assume there's pending output waiting to be flushed. Any ideas
or pointers on where to start digging would be much appreciated.
>How-To-Repeat:
Just boot...
>Fix:
n/a
