Hello, I tried all the suggestions from the list without success. Thanks to all. A memtest on my hostmachine didn't find any memory errors. I assigned more memory to the UML without success. There is still the problem with the sshd and mysqld segfaulting.
I found this in the gentoo wiki: "Configuring the guest kernel Gave up on this, see "Downloading Guest Kernel" above. If someone figures out a stable setup for the guest kernel running on a 2.6.10 host with the skas3 patch, let me know, and update this section." http://gentoo-wiki.com/HOWTO_User_Mode_Linux#Downloading_the_guest_kernel which seems to meet my scenario. I also have skas3 on the host and I tried with 2.6.8, 2.6.10, 2.6.11.6 and can't find a 2.6.x guest kernel (tried 2.6.9, 2.6.10, 2.6.11.6, please also see quote below) running stable on this host kernel. Are there any more suggestions on that problem? Otherwise I'll try some 2.4.x Kernel to find one running stable with my debian-sarge root_fs. Has anybody a combination of 2.6.x host and 2.6.x gueste kernel that works using skas (and maybe debian sarge rootfs)? Can you maybe provide infos on your versions and patches? regards Daniel ---------- Forwarded Message ----------- From: "Daniel Tombeil" <[EMAIL PROTECTED]> To: user-mode-linux-user@lists.sourceforge.net Sent: Fri, 8 Apr 2005 13:58:39 +0200 Subject: UML guest kernel 2.6.x problems Hi, I'm using UML on debian sarge. At the moment I'm using a hand build "Linux 2.6.8skas-v6 #1 SMP" on the host system (with patches from http://www.user-mode-linux.org/~blaisorblade/patches) and the guest kernel from debian unstable "2.4.26-3um". My rootfs is debian sarge made with rootstrap. My hostsystem is a Dual PIII/800, 1.5GB RAM, 70GB ICP RAID5. Now I tried to build up a 2.6 kernel for the guest systems. I tried 2.6.9, 2.6.10 and 2.6.11.6 with an without patches from the above URL. The kernel compiles fine an also boots up, but for example the sshd won't run with "UsePAM yes". Every login-attempt triggers the sshd to segfault. I wouldn't be that bad to change sshd_config not to use PAM but also my mysqld from debian-sarge won't come up with the 2.6 guest kernel. I also segfaults an couldn't even do a traceback in case of invalid pointers. I tried to do some debugging an it seems the some action called "umoven" short after a call to "mprotect" triggers the sshd to segfault. Does anybody have any hints on that? Is this a known problem or is this only related to my system? I googled for a while but didn't find any helpful links.
