Now for the "weird" part: The oops happens when doing "make install" for a piece of software (xine-ui media player) as *root*. No kidding, it does NOT happen when I compile the software and do "make install" as a normal user. This is 100% reproducible, here're some technical infos before I go on describing whe I did: http://nerdbynature.de/bits/2.6.22-rc7-git8/ I've compiled this software earlier, numerous times, always doing "make" as a user and "sudo make install" afterwards to install to /opt/xine. So when I now tried "make install" as a user I had to chown /opt/xine to the user of course. Even funnier: the dmesg output was captured when I was in runlevel 1 - here "make install" (as root) did produce an oops too, but the system did NOT panic. I typed "make install" a few times - always an oops, but no panic (in runlevel 1). The netconsole.log captured the panics as well, but the output is kinda messy (as always), I'll try to reformat the logfile a bit... When the Oopses started I checked memory (no memtest86 for ppc, but userspace memtest found nothing) and the harddisk (dd'ing from the whole disk) and fsck'ed the ext3 - not a single error. Also, all other applications are running fine (X11, music, video and stuff), the system is stable as usual. I even moved the old target-directory (make install...) out of the way and created a new one (new inode, new luck or so) - but to no avail. "fsck.ext3 -D" to reindex the directories, still the Oopses just won't go away. Searching the net for "Unrecoverable FP Unavailable Exception" did not return much :( Any ideas which magic syscall could cause these oopses? Thanks, Christian. -- BOFH excuse #409: The vulcan-death-grip ping has been applied.
