Why is that the printk output not going to syslog although I have entry in

kern.crit /var/log/pbsc.log
even after I remove the mdelay call.

Where as I am getting a log from another driver I am using. It also uses printk.

Does it mean that without using "testing" mode ( I cannot beacuse I need a
reboot) it is
not possible to get log ?

Thanks in advance

In order to log this message to syslog, you need to allow the syslog
process to run. If you're using a uniprocessor machine, using mdelay()
doesn't allow syslog to run during this time.

Softdog has a "testing" mode, which can be enabled by defining
ONLY_TESTING. This disables the automatic reboot, but the system
will log the timeout message.
