Sender: user-mode-linux-devel-admin@lists.sourceforge.net Errors-To: user-mode-linux-devel-admin@lists.sourceforge.net List-Unsubscribe: , List-Id: The user-mode Linux development list List-Post: List-Help: List-Subscribe: , List-Archive: Date: Tue, 12 Jul 2005 23:46:40 -0500 To: user-mode-linux-devel@lists.sourceforge.net So: I apply Blaisorblad's 2.6.12-bb2-skas0 rollup patch, build with skas support, and it crashes (as mentioned earlier) with: VFS: Mounted root (hostfs filesystem) readonly. Kernel panic - not syncing: get_skas_faultinfo : failed to wait for SIGUSR1/SIGTRAP, pid = 7944, n = 7944, errno = 0, status = 0xb And then a dump (which I pasted in a few messages back...) Is there an obvious way to track this down further? I ran it under strace and filtered out the setsigmask stuff, but unfortunately the result's not very interesting. Lots of stuff happens, then: waitpid(7944, [{WIFSTOPPED(s) && WSTOPSIG(s) == SIGSEGV}], WUNTRACED) = 7944 ptrace(PTRACE_GETREGS, 7944, 0, 0x88e1804) = 0 ptrace(PTRACE_GETFPXREGS, 7944, 0, 0x88e18b4) = 0 ptrace(PTRACE_CONT, 7944, 0, SIGSEGV) = 0 --- SIGCHLD (Child exited) @ 0 (0) --- waitpid(7944, [{WIFSTOPPED(s) && WSTOPSIG(s) == SIGUSR1}], WUNTRACED) = 7944 getpid() = 7939 ptrace(PTRACE_SETREGS, 7944, 0, 0x88e7764) = 0 ptrace(PTRACE_CONT, 7944, 0, SIG_0) = 0 --- SIGCHLD (Child exited) @ 0 (0) --- waitpid(7944, [{WIFSTOPPED(s) && WSTOPSIG(s) == SIGTRAP}], WUNTRACED) = 7944 ptrace(PTRACE_SETREGS, 7944, 0, 0x88e1804) = 0 ptrace(PTRACE_SETFPXREGS, 7944, 0, 0x88e18b4) = 0 ptrace(PTRACE_SYSCALL, 7944, 0, SIG_0) = 0 --- SIGCHLD (Child exited) @ 0 (0) --- waitpid(7944, [{WIFSTOPPED(s) && WSTOPSIG(s) == SIGSEGV}], WUNTRACED) = 7944 ptrace(PTRACE_GETREGS, 7944, 0, 0x88e1804) = 0 ptrace(PTRACE_GETFPXREGS, 7944, 0, 0x88e18b4) = 0 ptrace(PTRACE_CONT, 7944, 0, SIGSEGV) = 0 waitpid(7944, [{WIFSIGNALED(s) && WTERMSIG(s) == SIGSEGV}], WUNTRACED) = 7944 --- SIGCHLD (Child exited) @ 0 (0) --- ioctl(1, SNDCTL_TMR_TIMEBASE or TCGETS, 0x88e793c) = -1 ENOTTY (Inappropriate ioctl for device) write(1, "Kernel panic - not syncing: get_"..., 131) = 131 And so on through a ptrace of it dumping stack. Am I doing it right? Is there anything I can do to help track this down?
