Subject: [uml-devel] skas mode panic - ltrace strace
Date: Tue, 20 Jan 2004 19:20:42 +0800 [thread overview]
Message-ID: <20040120112042.GA2916@localhost> (raw)
Hi
I have a reproducible kernel panic running the ltrace program. The
panic only occurs when running the uml kernel in skas mode. mode=tt
does not panic.
Running as a normal (non root) user:
$ ltrace strace ls
results in:
Kernel panic: Kernel mode signal 5
Is anyone else able to reproduce this?
Details:
UML is debian woody, running vanilla kernel 2.4.22 with
uml-patch-2.4.22-5.bz2. Also tested is vanilla kernel 2.4.23 with
uml-patch-2.4.23-1.bz2. The kernel panic occures on both of these
setups.
Host is debian woody 2.4.22 with preemt, lowlatency and skas3 patches
applied.
The panic occurs because the syscall number gets set to -1. I have not
been able to track down exactly where this occurs, and any help on this
would be warmly received.
Dion.
