sys/modules/linux/linux_ioctl.o - LOR [I think]

Version: FreeBSD 6.0-CURRENT #1: Tue Feb 22 12:47:37 CST 2005

Seeing these error on console:

I'm suspecting a LOR with linux_base.

Other symptons include:

  Compilation of software hangs:

   e.g.

         c++ -c -pipe -fno-exceptions -fPIC -Wall -W -O2 -pipe -march=pentium4  -DQT_TABLET_SUPPORT -DQT_NO_DEBUG -DQT_THREAD_SUPPORT -DQT_SHARED -I/usr/local/share/qt/mkspecs/freebsd-g++ -I.  -I/usr/local/include/freetype2 -I../interfaces -I/usr/local/include -I../../../include -I.moc/release-shared-mt/ -o .obj/release-shared-mt/yyindent.o yyindent.cpp
      /usr/ports/x11-toolkits/qt33/work/qt-x11-free-3.3.3/bin/uic -L /usr/ports/x11-toolkits/qt33/work/qt-x11-free-3.3.3/plugins preferences.ui -i preferences.h -o preferences.cpp
      load: 0.19  cmd: uic 10399 [lockd] 0.05u 0.13s 0% 5572k
      load: 0.19  cmd: uic 10399 [lockd] 0.05u 0.13s 0% 5572k
      load: 0.22  cmd: uic 10399 [lockd] 0.05u 0.13s 0% 5572k

Other than that the box keeps running fine.

e.g.

     last pid: 10808;  load averages:  0.80,  0.43,  0.36 up 4+20:06:42  12:32:01
