RT patch version: patch-2.6.33.6-rt26.bz2 platform: x86_64 original discussion: https://bbs.archlinux.org/viewtopic.php?pid=797214 1. When booting, the kernel reports this error: (screenshot 220 kB ) http://www.beroal.in.ua/prg/linux/kernel26-rt-ice/kernel26-rt-ice-2.6.33-11-fail.jpg I did not see this error with a previous version of RT patch. I use the standard file "config*". Error is gone when "CONFIG_FTRACE=n" is set in "config*". 2. I experience random freezes. They occur approximately every day. OS is not freezed completely: Ctrl+Alt+F* works and the cursor blinks, but I can type nothing into "tty". Sometimes Ctrl+Alt+F* works only several times than OS freezes completely. Sometimes temporary (1-10 seconds) freezes occur and foreshadow an everlasting freeze. I run several application with real time CPU and I/O priorities and "mlockall". I can not associate any change in operation of those programs with freezes. Though I accustomed to these issues, it would be nice to solve them.
