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.
Interestingly, the issue does _not_ appear in the latest maverick.

Any ideas? I would prefer to avoid upgrading to maverick because of this.
