The previous DEBUG_SHIRQ patch missed one case. The console doesn't set its host descriptors non-blocking.
Sorry, things looked okay when I tested on my UML environment (Puppy Linux). Some xterms popped around (because I was using "con=xterm") and the system was usable, so it gave me no indication something was wrong.
I thought of adding an extra debugging option to warn us when a blocking I/O operation is issued for a socket/fd, but UML-specific code is not consistent regarding glibc functions. That is, most of the time it calls os_*(), but sometimes it calls functions like recvfrom() directly. I'll grep the source code for such calls and send a patch to clean it up a bit.
There might still be such cases, I haven't tested all channel types yet. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
