[Bug 427288] Re: Karmic i386 EC2 kernel emulating unsupported memory accesses
This problem is still present in lucid when using imagemagick (and I presume other packages), even though it does not appear when booting. To reproduce - launch "ami-a403f7cd" (latest lucid 32bit). dmesg output is clean - install the 'imagemagick' package - run 'convert' without any argument. The command takes 10+ seconds to run. After finishing dmesg output contains the following: ** WARNING: Currently emulating unsupported memory accesses ** ** in /lib/tls glibc libraries. The emulation is** ** slow. To ensure full performance you should ** ** install a 'xen-friendly' (nosegneg) version of ** ** the library, or disable tls support by executing ** ** the following as root: ** ** mv /lib/tls /lib/tls.disabled** ** Offending process: convert (pid=910) ** Deleting /lib/tls does not help.

[Bug 427288] Re: Karmic i386 EC2 kernel emulating unsupported memory accesses
I've just tested on ami-a40fefcd , which uses the kernel in question
that installing libc6-xen fixes this problem in ec2.
I booted the instance, then 'apt-get update && apt-get install
libc6-xen'. After a reboot, I have:
$ uname -r

Steve successfully debugged that /etc/ld.so.nohwcap existed and was
causing the problems. After removal of that file and 'ldconfig', a ldd
/bin/bash will show 'libc.so.6 => /lib/tls/i686/nosegneg/libc.so.6'

[Bug 427288] Re: Karmic i386 EC2 kernel emulating unsupported memory accesses
I tested this on ami-a40fefcd (alpha5.1) I verified that before install of libc6-xen, ldd reports bash to be using /lib/tls/i686/cmov/libc.so.6 . after install, it shows /lib/tls/i686/nosegneg/libdl.so.2. However, after a reboot, I still see the message. I suspect this is coming from initrd, or some early boot, and not used after that.
