It looks like the witness mutex debugging system crashed. This sort of thing tends to happen when the witness data structures become corrupt. A frequent cause of this is a module failing to destroy a mutex. I think the recent addition of the MTX_SYSINIT(linux_osname, &osname_lock, "linux osname", MTX_DEF); could be causing the problem, as I do not see how its getting torn down. Can you try the following patch (it may not even compile, I don't have a current box handy): (its obviously incomplete, just intended to see if it fixes the problem you are seeing) Drew Index: compat/linux/linux_mib.c =================================================================== RCS file: /home/ncvs/src/sys/compat/linux/linux_mib.c,v retrieving revision 1.19 diff -u -r1.19 linux_mib.c --- compat/linux/linux_mib.c 13 Mar 2003 22:45:43 -0000 1.19 +++ compat/linux/linux_mib.c 25 Mar 2003 23:05:08 -0000 @@ -50,7 +50,7 @@ SYSCTL_NODE(_compat, OID_AUTO, linux, CTLFLAG_RW, 0, "Linux mode"); -static struct mtx osname_lock; +struct mtx osname_lock; MTX_SYSINIT(linux_osname, &osname_lock, "linux osname", MTX_DEF); static char linux_osname[LINUX_MAX_UTSNAME] = "Linux"; Index: i386/linux/linux_sysvec.c =================================================================== RCS file: /home/ncvs/src/sys/i386/linux/linux_sysvec.c,v retrieving revision 1.116 diff -u -r1.116 linux_sysvec.c --- i386/linux/linux_sysvec.c 21 Mar 2003 19:49:34 -0000 1.116 +++ i386/linux/linux_sysvec.c 25 Mar 2003 23:07:36 -0000 @@ -885,6 +885,7 @@ &linux_glibc2brand, NULL }; +extern struct mtx osname_lock; static int linux_elf_modevent(module_t mod, int type, void *data) @@ -925,6 +926,7 @@ linux_ioctl_unregister_handler(*lihp); if (bootverbose) printf("Linux ELF exec handler removed\n"); + mtx_destroy(&osname_lock); } else printf("Could not deinstall ELF interpreter entry\n"); break; To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
