In an effort to test how well the kernel handles corrupted file systems (UFS2), I have run a series of test where I flip random bits in a file system, run fsck and then mount it. This has uncovered a few panics: panic: mount: lost mount panic: vm_fault: fault on nofault entry, addr: dda79000 panic: getblk: size(536871936) > MAXBSIZE(65536) panic: wrong length 1088 for sectorsize 512 panic: kmem_malloc(1342181376): kmem_map too small: 11620352 total allocated http://people.freebsd.org/~pho/stress/log/fs01.html http://people.freebsd.org/~pho/stress/log/fs02.html http://people.freebsd.org/~pho/stress/log/fs03.html http://people.freebsd.org/~pho/stress/log/fs04.html http://people.freebsd.org/~pho/stress/log/fs05.html I'm still not sure if this a reasonable test scenario and if it's worth pursuing? -- Peter Holm
