Message-ID: <f822aa1f0708191350k45269563u1422fc45d4f03fac@mail.gmail.com> Date: Sun, 19 Aug 2007 22:50:44 +0200 From: h.verhagen.web104@....nl To: linux-kernel@...r.kernel.org Subject: kernel BUG at lib/list_debug.c:27! Hi, According to dmesg, I encountered a kernel bug on my system. I'm not sure if this is the appropriate place to report this problem as this occured on a Fedora kernel. Maybe its a general problem? kernel BUG at lib/list_debug.c:27! invalid opcode: 0000 [2] SMP =========================================== = What was I doing when this happened. ========================================== I was doing a rm -rf /media/somedir/ command on a USB harddisk. This USB harddisk casing contained a flaky IDE harddisk. (smartd had been giving warnings about this drive for a while, that it was about to break doing. What happened. The rm stuck, (couldn't be killed, even with a kill -9 command). dmesg showed a kernel bug. =================================== = Version ==================================== Fedora core 7.
