Message-ID: <alpine.SOC.1.00.1207242330050.16040@math.ut.ee> Date: Tue, 24 Jul 2012 23:38:37 +0300 (EEST) From: Meelis Roos <mroos@...ux.ee> To: Linux Kernel list <linux-kernel@...r.kernel.org>, sparclinux@...r.kernel.org Subject: 3.5: kernel BUG at mm/mmap.c:2313 (on sparc64) While testing Debian update on fresh 3.5 kernel on Sun Ultra 2 (sparc64), got the above BUG during generation of initramfs. The machine last run 3.5-rc7 and some previous rc-s fine, as well as earlier 3.x releases. Rerunning this initramfs generation after reboot worked fine, I cannot reproduce the problem.
