I've just had a scary experience, they are fortunately rare! :-) I'm running what is now Debian Stable, a self-compiled but unpatched Debian 2.6.8-16 kernel. The first symptom I saw was that Emacs segfaulted on me and while I was pondering how scary _that_ was, the whole system froze on me. Rebooting, I saw the following in kern.log. Since it shouts it is a kernel bug, I took that as invitiation to post here. My paste begins before the "cut here", as I just before the crash experienced problems when using a PL-2303 converter. I got a new USB2/FireWire card in the door yesterday, and there were apparently problems with using the pl2303 with it. It still works fine with the old USB1 on my mobo. I have no idea if it is relevant, but I thought I'd include it. I haven't included my .config though, this message is large enough as it is, I suppose... It is of course available upon request, but please CC any replies, I'm not subscribed. Here is the kern.log excerpt: Jun 12 14:52:53 owl kernel: pl2303 1-3.1:1.0: PL-2303 converter detected Jun 12 14:52:53 owl kernel: usb 1-3.1: PL-2303 converter now attached to ttyUSB0 Jun 12 14:52:53 owl usb.agent[4337]: pl2303: already loaded Jun 12 14:52:53 owl udev[4361]: configured rule in '/etc/udev/rules.d/compat-full.rules[8]' applied, added symlink '%k' Jun 12 14:52:53 owl udev[4361]: configured rule in '/etc/udev/rules.d/devfs.rules[46]' applied, 'ttyUSB0' becomes 'tts/USB%n' Jun 12 14:52:53 owl udev[4361]: creating device node '/dev/tts/USB0' Jun 12 14:53:01 owl /USR/SBIN/CRON[4376]: (mail) CMD ( if [ -x /usr/lib/exim/exim3 -a -f /etc/exim/exim.conf ]; then /usr/lib/exim/exim3 -q ; fi) Jun 12 14:53:16 owl kernel: PL-2303 ttyUSB0: pl2303_open - failed submitting interrupt urb, error -28 Jun 12 14:53:16 owl kernel: PL-2303 ttyUSB0: PL-2303 converter now disconnected from ttyUSB0 Jun 12 14:53:16 owl udev[4382]: removing device node '/dev/tts/USB0' Jun 12 14:57:15 owl kernel: usb 1-3.1: USB disconnect, address 6 Jun 12 14:57:15 owl kernel: pl2303 1-3.1:1.0: device disconnected Jun 12 14:57:30 owl kernel: usb 2-2: new full speed USB device using address 2 Jun 12 14:57:30 owl kernel: pl2303 2-2:1.0: PL-2303 converter detected Jun 12 14:57:30 owl kernel: usb 2-2: PL-2303 converter now attached to ttyUSB0 Jun 12 14:57:31 owl udev[4509]: configured rule in '/etc/udev/rules.d/compat-full.rules[8]' applied, added symlink '%k' Jun 12 14:57:31 owl udev[4509]: configured rule in '/etc/udev/rules.d/devfs.rules[46]' applied, 'ttyUSB0' becomes 'tts/USB%n' Jun 12 14:57:31 owl udev[4509]: creating device node '/dev/tts/USB0' Jun 12 14:57:31 owl usb.agent[4493]: pl2303: already loaded Jun 12 14:57:55 owl kernel: Assertion failure in __journal_drop_transaction() at fs/jbd/checkpoint.c:618: "transaction->t_updates == 0" Jun 12 14:57:55 owl kernel: ------------[ cut here ]------------ Jun 12 14:57:55 owl kernel: kernel BUG at fs/jbd/checkpoint.c:618!
