Can you try flipping it? klausman@gentoo.org 2007-08-06 14:16:43 0000 It wasn't active and I set it to "N", then when executing "make all", I said "N" to the OProfile Config option.

It cancelled the need for CONFIG_PROFILING=y but it still dies on the psmouse file. phreak@gentoo.org 2007-08-19 11:35:00 0000 OK, the patch is finally applied upstream (see URL). klausman@gentoo.org 2007-08-19 12:58:37 0000 Upstream has done only half-a-fix.

I have not tried to boot the resultant kernel yet, however. Tested with 2.6.23.9 vanilla kernel in an ia64 cross compile environment (on x86) with a hacked ebuild of gcc-4.2.2. halcy0n@gentoo.org 2007-12-08 17:41:00 0000 This is really a GCC bug that is being addressed upstream. http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31490 dsd@gentoo.org 2008-02-09 16:22:00 0000 Hmm? people seem to think its a kernel issue now. http://www.gossamer-threads.com/lists/linux/kernel/876795 klausman@gentoo.org 2008-02-20 18:55:19 0000 This is fixed by changeset 91d35dd93e14c34539a8005183ea500f25caad02 which is part of 2.6.25-rc2. armin76@gentoo.org 2008-02-21 12:05:57 0000 I confirm... dsd@gentoo.org 2008-02-24 23:37:33 0000 queued for 2.6.23 and 2.6.24 dsd@gentoo.org 2008-02-26 17:10:24 0000 Fixed in genpatches-2.6.23-10 (gentoo-sources-2.6.23-r9) and genpatches-2.6.24-4 (gentoo-sources-2.6.24-r3)
