Great, this is something usable:)

Unfortunatelly, it didn't work for me. It compiled and booted fine. But
when I tried to just copy the kernel tree (~300MB), various kernel
threads crashed with BUGs (like kswapd0) and such things. Sometimes it
looked like there is no problem, just that the console was flooded with
messages from ccache (cc_writepage), but without any error indication,
just that the machine almost hanged (it was alive but no new processes
could run). I tried various sizes for ccache (from 200MB to 10MB as
adviced above), I have 320MB RAM. I can provide the crash dump, stack
trace, offending functions, if you anybody is interested and I write
them down on paper.
What do I do wrong? Can ccache be sensitive to various kernel tweaking
options, e.g. preemption, irqstacks, debugging? May it conflict with the
suspend2 patch (www.suspend2.net, but I don't think that patch does
anything while the system is running). I'll try more and let you know.
Thanks,
Peter
