| |
Hi, all. I've had at least two reports of errors like: kmod: waitpid(%d,NULL,0) failed, returning = -512.
when using 2.1.11x kernels with my devfs patch (and apparently the errors go away when devfs is not used). Something I'm trying to establish whether anything *actually fails* when this message pops up. I'm starting to suspect that it's an annoying message and nothing more: no functionality is lost.
Secondly, I also suspect that devfs *is not* causing these messages. Rather, using devfs increases the incidence of calls to request_module(), and hence you're more likely to see these messages, because there is still an underlying problem with kmod. Therefore I would dearly like to hear from people who *don't* use devfs but still get these error messages. I'd also like to know if the message is associated with any actual failures in operation, or if it's just an annoying message.
I had originally suspected a nasty deadlock problem with the /dev directory semaphore, but having run strace(1) on modprobe(1), I don't see how that can be happening.
Regards,
Richard....
