I compiled a custom kernel with the above settings and this one seems
to work, at least not freezing (more later).
However, after install of the pcmcia kernel modules to the previously
fully functional iso-cd kernel, the newer (Apr 14) 2.4.18-bf2.4
(2.4.18-5 based) was installed (not the kernel supplied with trial
iso-cd, Mar 30) showing the _same_ problems with apic as -686
(2.4.18-5). A diff between the log messages of the iso-cd imge and the
-bf2.4 image boot messages are given below. Sorry that I don't have
the config file of the older (iso-cd) kernel anymore, it has been
A few questions remain:
1. Which configuration settings to use to get the 'noapic' kernel
option to work? No sucess with any on the stock kernels,
2.4.18-bf.2.4 and 2.4.18-686 which are both set up with:
aln 2.4.18-686 also with:
2. Using the custom kernel (2.4.18-10.0.0.Custom) After for example a
suspend and when running in X, the mouse (touchpad) goes nuts :(
Switching back and forth to a virtual terminal does _not_ help,
neither does an exit from X. A reboot is the only way out. Can this
be due to problems with gpm interaction? Anything else?
