Hi uml-people

I have problem with hostkernel 2.6.12-skas3-v8.2 to start a guest. This is the output:

./2.4.29 eth0=tuntap,tap_bf,00:11:2F:87:09:02 ubd0=debian20gigg.iso mem=512M

and the hangup is here:
kjournald starting. Commit interval 5 seconds
EXT3-fs: mounted filesystem with ordered data mode.
VFS: Mounted root (ext3 filesystem) readonly. Mounted devfs on /dev

(I get nothing after "mounted...")

And in top I get 100% cpuusage for that guest-pid.

Can someone point me in the right direction.

And I also have problem with jdk 1.{4,5} on 2.4.X-guestkernels Is there a known problem with 2.4.X + jdk 1.{4,5} ?

Best Regards
Rickard Vikström

That could be a console setup problem, but

Ok, that's bad, yes. But please try 2.4.28-bs2 and say the *guest* version (including the patch version). There are some problems with 2.4.27-1um.

That said, UML 2.4 is more problematic in general, and more buggy, than UML/2.6. Try to use the -bs patches for 2.6 too. And report any problem you get with 2.6, we might be able to fix them.

Try 2.4.28-bs2 - on other releases there are known problems, yes.
