I've got a 4.9 machine that's acting as a router and is lightly loaded otherwise. (There are a significant number of interrupts from network interface cards at all times, but disk usage is normally quite light.) When I typed make depend; make; make install to rebuild the kernel, the system had a panic during the "make" phase. Upon rebooting, I got a message saying that there was a "unexpected softupdates inconsistency" in /usr. After running fsck (which reported a large number of problems), I found that all of the files in the lost+found directory were (maybe not surprisingly) dependency files. I repeated the build, doing nice make clean; sync; sleep 10; nice make depend; sync; ... and this time the kernel built with no problems. I suspect (though I don't have a backtrace) that heavily loading the file system and/or the ata driver in the presence of many other interrupts can cause a panic which softupdates is not prepared to handle. Have others seen this? --Brett Glass
