[LAU] apt-get and RT kernel

Hi, I have an oddity on Ubuntu Lucid. Installing libboost1.40-dev, default kernel, no problemo. Installing libboost1.40-dev, RT kernel, install (unpacking/ processing) takes minuts! I have this oddity with another package, but most packages install normal. $ uname -a Linux ubuntu 2.6.33-29-realtime #1-Ubuntu SMP PREEMPT RT Wed Aug 4 20:14:20 UTC 2010 i686 GNU/Linux from: https://launchpad.net/~abogani/+archive/ppa/ $ apt-cache policy libboost1.40-dev libboost1.40-dev: Installed: 1.40.0-4ubuntu4 Candidate: 1.40.0-4ubuntu4 Version table: *** 1.40.0-4ubuntu4 0 500 http://nl.archive.ubuntu.com/ubuntu/ lucid/main Packages 100 /var/lib/dpkg/status (maybe not interesting, but iotop says: CONFIG_TASK_DELAY_ACCT not enabled in kernel, cannot determine SWAPIN and IO %) Regards, \r
