A few days ago, I started to get frequent panics on a laptop running 9.2-RELEASE. The message is: panic: ffs_valloc: dup alloc and the backtrace from the core.txt file is: KDB: stack backtrace: #0 0xc0b1810f at kdb_backtrace+0x4f #1 0xc0adf38f at panic+0x16f #2 0xc0d102d4 at ffs_valloc+0x5a4 #3 0xc0d50384 at ufs_makeinode+0xa4 #4 0xc0d50c80 at ufs_create+0x30 #5 0xc0f73b02 at VOP_CREATE_APV+0xa2 #6 0xc0b8e3f6 at vn_open_cred+0x246 #7 0xc0b8e87b at vn_open+0x3b #8 0xc0b89ccc at kern_openat+0x1ec #9 0xc0b8a0e5 at kern_open+0x35 #10 0xc0b8a120 at sys_open+0x30 #11 0xc0f4ce53 at syscall+0x443 #12 0xc0f36661 at Xint0x80_syscall+0x21 Uptime: 7m7s Physical memory: 2965 MB Dumping 160 MB: 145 129 113 97 81 65 49 33 17 1 I don't really have any experience with FreeBSD kernel dumps, so I don't know how to pick out what's important. How do I proceed to resolve this problem? (Also note that I have 9.1-RELEASE installed on the same machine on a different slice which is stable, so I think hardware problems are not likely to be a factor.) -- Will
