kernel26-rt-ice 2.6.33-11 error at boot and random freezes

1. When booting, the kernel reports this error: screenshot 220 kB. Commenting lines in PKGBUILD revealed that "Applying realtime patch" is to blame. I use the standard file "config*". Error is gone when "CONFIG_FTRACE=n" is set in "config*".

2. With 2 versions of "kernel26-rt-ice" 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.

platform: x86_64
package: kernel26-rt-ice

Though I accustomed to these issues, it would be nice to solve them. Whom I should report to, who can help?

The rt patch does that once in a while. You'd have to ask them about it, their mailing list isn't very active but once a question comes up people will help.

It seems that no one even noticed my message in "Linux RT Users".

Ah well, you could try using an earlier version of the patch (just modify the PKGBUILD to point to the old version, make sure to alter the kernel version as well). Ask here for help if needed, or email me directly.

I appreciate your help. Actually I need a person that is deep in the RT patch and is willing to work closely. It would be better if we just wait for that kind of a person. wink
