Hi, Yes, I realise that the "dpkg" and "sync" binaries make system calls into the kernel but I thought it might be appropriate to report a bug with "coreutils" because of the interaction between "sync" and "dpkg". > Also, the kernel OOPS trace suggests the *kernel* got hung while > performing a sys_sync() call (and yes, I agree that it is probable both > coreutils and dpkg would end up in the same kernel path). So... whatever > happened seems to have happened below either utility. OK, I should have reported this as a kernel bug not a "coreutils" bug. > I wonder if you have remote filesystems, or some sort of disc/filesystem > issue.

I'm running the nfs-kernel server, but the systems concerned have all been running without any "sync" or "dpkg" problems until just recently. An important point is that the coreutils "sync" command works properly on my server unless "dpkg" is deadlocked after a timeout attempting to sync() the filesystem, in which case the coreutils "sync" then blocks.
