Hi !
Since one or two weeks my system panics shortly before completely
going down. Services like squid and inn take a little longer than
usual to finish, I hear much disk activity.
This happens usually if the system ran a day or so.
What can I do to help ? Compile Kernel with debug infos ?
BTW, yes I run an ELF kernel. Can't say exactly, if it's behaving
like this after completely migrating to ELF.
