[uml-devel] latest cross-build patch break UML build, when using -j2

[uml-devel] [Bug 49277] Compile of usermode-sources-2.6.x fails
http://bugs.gentoo.org/show_bug.cgi?id=49277 --- Additional Comments From [EMAIL PROTECTED] 2005-02-18 05:05 PST --- Thanks for the explanation- thats good news. So, when Linux 2.6.11 comes out and gets marked stable in portage, we will effectively be able to drop usermode-sources-2.6 from portage without losing any functionality? --- You are receiving this mail because: --- You are on the CC list for the bug, or are watching someone who is. --- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

Trying with the above patch in now only get two "sleeping function called from invalid context" warnings during boot and none during running. However I get a lot of those errors: arch/um/drivers/line.c:262: spin_lock(arch/um/drivers/line.c:085b5900) already locked by arch/um/drivers/line.c/262 Also both before and after the patch I see a lot of messages like: kernel: line_write_room: tty2: no room left in buffer Best regards, Anton -- Anton Altaparmakov (replace at with @) Unix Support, Computing Service, University of Cambridge, CB2 3QH, UK Linux NTFS maintainer / IRC: #ntfs on irc.freenode.net WWW: http://linux-ntfs.sf.net/ & http://www-stu.christs.cam.ac.uk/~aia21/ --- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
