savecore: bad magic number, savecore -L hangs
I'm running OI 151 on amd64 (http://pkg.openindiana.org/dev-il/) and while I tried to savecore a kernel dump, it tells me
(583) oldn90700:/root# savecore -v
savecore: bad magic number ba5fbbf7
Just to verify that kernel dumps are written correctly, I tried savecore -L:
(584) oldn90700:/root# savecore -L
dumping to /dev/zvol/dsk/rpool/dump, offset 65536, content: all
1:29 99% done
and here it hangs until eternity...at least truss -fpi `pgrep savecore` does not show anything, so it seems to hang in a syscall.
I can however attach to a running kernel via mdb -k and also break the machine while running the kmdb.
This sounds like http://wesunsolve.net/bugid/id/6996868 to me...
