Hi,
got a panic with the kernel/world from today 10:53 UTC on amd64:
panic: softdep_deallocate_dependencies: dangling deps at line ...
... sys/ufs/ffs/ffs+softdep.c
cpuid=0;
--- code ---
/*
* Called whenever a buffer that is being invalidated or reallocated
* contains dependencies. This should only happen if an I/O error has
* occurred. The routine is called with the buffer locked.
*/
static void
softdep_deallocate_dependencies(bp)
struct buf *bp;
{
if ((bp->b_ioflags & BIO_ERROR) == 0)
panic("softdep_deallocate_dependencies: dangling deps");
softdep_error(bp->b_vp->v_mount->mnt_stat.f_mntonname, bp->b_error);
panic("softdep_deallocate_dependencies: unrecovered I/O error");
}
--- /code ---
happening every boot now when background fsck is running; machine
previously crashed once with new kernel and old fsck.
can reproduce it every reboot when not killing autoboot script fast
enough;
don't have serial console :( so here is the handwritten output of
