supressed kernel messages?
Last modified: 2005-09-09 10:44:07 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?
Btw, I don't think this is a MAJOR bug :/
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)
the loglevel can be adjusted in /etc/sysconfig/kernel Variable: KERNEL_LOGLEVEL
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...
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.
Just try kernel parameter "debug"
and I can load and unload acx_pci without a problem ... probably beacause I do not have the hardware.
ok, we have listed all possible ways of getting more debug output from the kernel ... -> worksforme
