Hello, I can run imnues under 8-STABLE amd64 with the patchset imunes-8.0-RC3.diff. But if I terminate any simulation, the system panics. # vimage -lr i0aa50 i0aa50.n0 i0aa50.n1 i0aa50.n2 i0aa50.n3 i0aa50.n4 i0aa50.n5 i0aa50.n6 i0aa50.n7 i0aa50.n8 i0aa50.n9 The moment the system panics with the satatusline reporting, the last nodenumber on the simulation. I failed to genearte the panic by creating and destroying hierachical vimages with "vimage". So removeing the simulation is sane by the shell: # vimage -d i0aa50 But still Imnunes generates a panic on "termination" of the simulation. Any idea how to workaround this? What does Imnues do after cleaning up the vimage stuff. My tcl has become a bit rusty. kind regards Dirk - Dirk Meyer, Im Grund 4, 34317 Habichtswald, Germany - [dirk.meyer@dinoex.sub.org],[dirk.meyer@guug.de],[dinoex@FreeBSD.org] http://people.freebsd.org/~dinoex/errorlogs/ Unread portion of the kernel message buffer: if_delmulti_ifma: ifnet 0xffffff0005813800 disappeared if_delmulti_ifma: ifnet 0xffffff0005813800 disappeared if_delmulti_ifma: ifnet 0xffffff0005813800 disappeared if_delmulti_ifma: ifnet 0xffffff00058a3800 disappeared <6>ifaddr cache = 0xffffff0040148c00 is deleted <6>ifaddr cache = 0xffffff0005618b00 is deleted if_delmulti_ifma: ifnet 0xffffff00058a3800 disappeared if_delmulti_ifma: ifnet 0xffffff00058a3800 disappeared if_delmulti_ifma: ifnet 0xffffff00058a3800 disappeared if_delmulti_ifma: ifnet 0xffffff00058a3800 disappeared panic: unrhdr has 1 allocations cpuid = 0 Uptime: 37m26s Physical memory: 4041 MB Dumping 1310 MB: 1295 1279 1263 1247 1231 1215 1199 1183 1167 1151 1135 1119 1103 1087 1071 1055 1039 1023 1007 991 975 959 943 927 911 895 879 863 847 831 815 799 783 767 751 735 719 703 687 671 655 639 623 607 591 575 559 543 527 511 495 479 463 447 431 415 399 383 367 351 335 319 303 287 271 255 239 223 207 191 175 159 143 127 111 95 79 63 47 31 15 Reading symbols from /boot/kernel/acpi_ibm.ko...Reading symbols from /boot/kernel/acpi_ibm.ko.symbols...done. done.
