Hello, I had a kernel panic on my 2.2.8 system a few days ago; just thought I'd tell you about it. You might think I'm totally stupid after reading my description of what caused it, and I probably was at the time: it was sometime around 4.30am... I was running two programs that both use mmap() on the same 500MB file. I killed one of the programs and forgot about the other, and wanted to delete the file and make a new one with all zeros. Deleting the file made it disappear from the directory listing allright, but didn't free up any disk space, so I couldn't create a new 500MB file on that partition. Hmmmm... What to do? Well, I did fsck on the live filesystem and answered yes on the question of whether I wanted to recover 500MB of "lost" file space. Then, I suddenly remembered that other program running, and well, of course I realized why the space for the file hadn't been available earlier... Anyway, I killed that other program too, which had the kernel panic. I sort of think that a kernel panic is a bug, regardless of the level of stupidity needed to trigger it. Any comments?
