History ------- Nearly two month ago /var and /tmp got lost by hdd crash. I did my best to recover the lost data by re-installing most of the packages, including aaa-base, aaa_base-extras, kernel etc., because a sufficient backup of this two dirs was not available :(.

Since the hdd crash I notified that 32bit apps response with Bad system call, even if they were updated or re-installed. See the example of acroread below.

What can I do else to solve this behaviour, apart from a completely fresh install?

Every hint to solve this problem is highly appreciated.

Shot in the dark, but it sounds similar to https://bugzilla.redhat.com/show_bug.cgi?id=1219884.

Hi Andrei, many thanks for the link. But ... My "32bit apps response with Bad system call"-problem is continuous. A new generated initramfs image doesn't help. There are no missing 32bit package reported by zypper/rpm. But I'm unsure if this is really true. Since the crash some packages were reported as not installed by zypper, whilst the binaries were in path. I've updated such package asap I found them. May be there are more. strace shows for both 32bit apps the same: +++ killed by SIGSYS +++, see below. Any other idea?

Shot in the dark if you execute one of the following command lines, do you see the EMULATION=y output?

...

zgrep IA32_EMU /proc/config.gz CONFIG_IA32_EMULATION=y

or

...

gunzip

I.e. it's possible to create a kernel that doesn't support IA32 emulation, so no matter what 32-bit rpms you have loaded, it won't work.

Thank you for your suggestion, Linda. The "Bad system call" problem was solved on [opensuse-factory] meanwhile. Now I get: raven:~ # zgrep IA32_EMU /proc/config.gz CONFIG_IA32_EMULATION=y /proc/config.gz:CONFIG_IA32_EMULATION=y gzip: CONFIG_IA32_EMULATION=y.gz: No such file or directory raven:~ # gunzip
