Description Ioana Josephine Ciuca 2005-08-27 19:16:18 UTC

With beta kernels, when loading for example acx_pci, I get no messages in dmesg
or /var/log/messages. With other kernels, I simply get usefull debugging
information in the messages. Even when loading sky2 modules, i only get "sky2
eth0: enabling interface"; but when the module crashes, nothing is to be found
in dmesg or other logs. This leads to failing in making my acx111 card working.

I'm not aware of any removed or suppressed kernel messages. Maybe somebody is
changing the kernel log level from user space. Rudi, any idea?

Comment 2 Hubert Mantel 2005-08-31 15:38:09 UTC

Btw, I don't think this is a MAJOR bug :/

Comment 3 Ruediger Oertel 2005-08-31 16:15:18 UTC

is the kernel really the only thing that differs here ? 
of course different boot-scripts can have different effects ... 
 
btw: that can be changed any time at runtime: 
echo 7 > /proc/sysrq_trigger 
(or just ALT+SYSRQ-7 if sysrq is enabled)

Comment 4 Ruediger Oertel 2005-09-01 10:17:30 UTC

the loglevel can be adjusted in 
/etc/sysconfig/kernel Variable: KERNEL_LOGLEVEL

Comment 5 Ioana Josephine Ciuca 2005-09-02 21:05:23 UTC

Tried that. Still no luck. And without a decent logging I am not able to
identify why rmmod acx_pci hangs in a D-state...neither fix my not-working
acx111 wifi card...and so on.
At least you could have tried probing what I wrote here (loading and unloading
acx_pci) and see what i refer to.

Thanks for the support...

Comment 6 Ruediger Oertel 2005-09-08 13:25:24 UTC

maybe this is even before the boot-scripts set the loglevel. 
 
Hubert: isn't there a cmdline option for the kernel, to set the 
initial loglevel to debug.

Comment 7 Hubert Mantel 2005-09-08 13:32:53 UTC

Just try kernel parameter "debug"

Comment 8 Ruediger Oertel 2005-09-08 22:27:47 UTC

and I can load and unload acx_pci without a problem  
... probably beacause I do not have the hardware.

Comment 9 Ruediger Oertel 2005-09-09 10:44:07 UTC

ok, we have listed all possible ways of getting more debug output 
from the kernel ... -> worksforme
