In fact it happens with sid, with ppc64 too, but not with m68k and sh4.
And only with "unshare --pid --fork".
Without "unshare", the result is:
Unsupported ioctl: cmd=0x80047476
bash: cannot set terminal process group (11507): Function not implemented
bash: no job control in this shell
Unsupported ioctl: cmd=0x80087467
Unsupported ioctl: cmd=0x80087467

I'm just now getting back to this, and cannot replicate the issue
... Oh nevermind. I should be expecting no "unsupported" at all, since that's
what we get with master.
The cause is that "cmd" accidentally changed from "int" in the do_ioctl
parameter list to "abi_ulong" as a local variable in impl_ioctl. This caused a
table lookup failure on any ioctl with bit 31 set, for 64-bit guests.
Do you plan to send a new version of this series?
Thanks,
