The screen shot (just a photo, b/c nothing was in the syslog) can be downloaded here [1]. The last action before I left the machine for a while was to start a user mode linux (stale 32 bit Gentoo, kernel v3.9-rc3-324-g5da273) and run trinity within that system. Please note that the host kernel crashed (UML probably too). To feed trinity with victim files I NFSv4 mounted a directory located at the host system under /tmp onto a mount point of the UML system (all file systems are EXT4). That directory contained 100 files and 100 directory. The trinity command line I used in the UML was : $> trinity --children 4 --victims /mnt/nfs/n22/forT -x mremap -x clock_nanosleep FWIW : mremap gives within an UML guest with kernel 3.9-rcX this [2] using SLAB and with SLUB this [3]; clock_nanosleep only slows down the tests [1] http://ompldr.org/vaHV6YQ [2] http://thread.gmane.org/gmane.linux.kernel/1462272 [3] http://sourceforge.net/mailarchive/forum.php?thread_name=5140E36D.2080606%40gmx.de&forum_name=user-mode-linux-user -- MfG/Sincerely Toralf Förster pgp finger print: 7B1A 07F4 EC82 0F90 D4C2 8936 872A E508 7DB6 9DA3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
