Re: I can't generate a kernel crash core.

I have been debuging this problem with gdb and printfs in the source for locate the path. I have found it fails in: arch/amd64/amd64/machdep.c:dodumpsys does: psize = bdev_size(dumpdev); kern/subr_devsw.c:bdev_size calls rv = (*d->d_psize)(dev) In my case the dev has major 0 and minor 1 (gdb)

Re: I can't generate a kernel crash core.

If the kernel hash a panic, the dump is captured, etc. and it works ok (kern.dump_on_panic=1). I can't generate a crash dump of a running system. On Sun, Jan 24, 2016 at 10:28 PM, Jose Luis Rodriguez Garcia wrote: > It is NetBSD 7.0 amd64 > > The swap size is 8 GB, and the

I can't generate a kernel crash core.

It is NetBSD 7.0 amd64 The swap size is 8 GB, and the memory of the PC is 4GB. This the /etc/sysctl.conf file: pc2$ grep -v '^#' /etc/sysctl.conf ddb.onpanic?=0 kern.ipc.shmmax=16000 vfs.generic.usermount=1 machdep.sparse_dump=1 kern.dump_on_panic=1 I have tried with: reboot 0x100 reboot
