Subject: binfmt_misc: hangs in syscall with x86 userland on x86_64 kernel
Date: Tue, 06 Sep 2011 10:55:19 +0200 [thread overview]
Message-ID: <1315299323.7365.10.camel@localhost.localdomain> (raw)
hello,
something in the binfmt_misc filesystem system seems to be broken when
trying to use this driver with an x86 user land on an x86_64 kernel.
the command "ls /proc/sys/fs/binfmt_misc" seems to hang in the stat64
syscall:
> stat64("/proc/sys/fs/binfmt_misc", 0x8bf68e8) = -1 EINTR (Interrupted system call)
> --- {si_signo=SIGINT, si_code=SI_KERNEL, si_value={int=1248448068, ptr=0x4a69ce44}} (Interrupt) ---
> +++ killed by SIGINT +++
I had to remove the systemd-binfmt register service from my default
runlevel to get to a shell/X11.
any ideas what's going on here?
the program "systemd-binfmt" seems to hang in this open() syscall:
> open("/proc/sys/fs/binfmt_misc/status", O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE|O_CLOEXEC, 0666) = -1 EINTR (Interrupted system call)
> --- {si_signo=SIGINT, si_code=SI_KERNEL, si_value={int=1248448068, ptr=0x4a69ce44}} (Interrupt) ---
> +++ killed by SIGINT +++
with kind regards
thomas
