Re: 2.6.23-rt1 lockup after loading HAL deamon

Hi

I enabled netconsole but I am affraid that it won't help. In attachment
I am sending complete log over netconsole. While I was trying to make
everything, I got a lockup on linux-2.6.23-rc8, but I am not sure into
this. But all lockups happend in VGA console mode. Any ideas.
