Hello,
I've tried to start Linux under Fiasco-UX. But I got:
l4lx | The running kernel does not have the l4lx | segments l4lx | feature enabled!
So I compiled the kernel with support for "Handle and preserve segments". But now I get a kernel bug when trying to start it.

Please tell us more: Show the revision date of you Fiasco and the date you last updated L4Linux-2.6.

I've checked out the source last week.
I've tried also a cvs co today but didn't worked. The co didn't go on after a while (no error msg). I cancelled it after several hours of idle time.

Hmm, that's interesting. Could be a pending CVS lock file but I did not find one after a quick look. Please try again, I think that we've fixed a segment issue this week. But it is also possible that the changes are not yet visible at the "outside". Therefore I put the file
http://os.inf.tu-dresden.de/~fm3/fiasco-20050628.tgz
online. Please try this.

Can you make your unstripped fiasco image (kernel.image) available somewhere?

Looks like this version misses the fix we did some days ago but besides that it starts bootstrapping L4Linux for me.
Which host kernel do you run? Any special patches applied?

I've used the the cvs sources from last week and the patch that Frank Mehnert posted.
Today I checked out the new sources. This time it worked. At least I can start Fiasco.
There are still bugs in the cvs:
in l4/pkg/nethub/server/src/Makefile:
"ifneq ("$(WITHOUT_CRYPTO)$(USE_L4CRYPTO)","y")"
should that no be "ifneq ("$(WITHOUT_CRYPTO)$(USE_L4CRYPTO)","yn")"?
The new dmon package in the cvs requires a petze package which is not available (yet ?).
Which host kernel do you run? Any special patches applied?
It's a Linux 2.6.10 kernel with SMP and HT support. No special patches.

Thanks.

Hmm. We will investigate that.

SMP and HT does not work with our L4Linux so it is better to disable these config options.

Forget this, Adam told me that this is your host kernel and not L4Linux...

Fixed it in local CVS by disabling Petze support by default (patch attached). It will be in remote CVS soon.
