[varenet@envy ~]$ uname -a Linux envy 2.4.27-1-mckinley #1 Fri Sep 3 13:33:45 MDT 2004 ia64 GNU/Linux unfortunately i can't run ksymoops anymore. This system is under high load and has to be quickly restored to a working state. The partition containing the troublesome folder has been reinitialized (though neither fsck nor badblocks shown anything wrong with it). Again, i have some more reports: back to the SMP box (2.6.8.1-1-mckinley-smp), i tried again to build gcc-3.4_3.4.2-2ubuntu1. The build that failed on the 2.4 UP box. It seems that i've been able to reproduce the "stall effect". Several tests from the ADA testsuite are getting stalled for no apparent reason. The only common thing is that they ALL get stuck issuing an Unaligned Access with the SAME ip. (See the inlined dmesg output). I had to kill those processes using SIGKILL, since SIGTERM had no effect. Two things about this: 1) The PID (?) shown between parenthesis in this dump differs (it's greater) with the PID reported in PS. These tests are single-threaded. 2) The ip looks like a shared lib, and ldd showed the following: libgnarl-3.4.so.1 => not found libgnat-3.4.so.1 => not found libpthread.so.0 => /lib/tls/libpthread.so.0 (0x2000000000040000) libc.so.6.1 => /lib/tls/libc.so.6.1 (0x2000000000070000) /lib/ld-linux-ia64.so.2 => /lib/ld-linux-ia64.so.2 (0x2000000000000000) unfortunately before i could change LD_LIBRARY_PATH, the build went over and the executable were gone. Only the ADA testsuite was affected. The rest of the build went mostly fine (i had troubles at the very end of the process, with dpkg-*, but i don't think this is related).
