Message-Id: <201104261815.p3QIF3CF028959@demeter1.kernel.org> Date: Tue, 26 Apr 2011 18:15:03 GMT From: bugzilla-daemon@...zilla.kernel.org To: linux-ext4@...r.kernel.org Subject: [Bug 25832] kernel crashes when a mounted ext3/4 file system is physically removed https://bugzilla.kernel.org/show_bug.cgi?id=25832 --- Comment #78 from Alan Stern <stern@...land.harvard.edu> 2011-04-26 18:15:00 --- I can report triggering a similar problem -- once. I attached a USB drive with an ext4 filesystem, mounted it, read a file from it, unbound usb-storage, and then unmounted it. No desktop was running at the time. About a second later I got a nasty crash -- an unending stream of log messages scrolling up the console, with no way to stop it other than powering off the machine. So then I rebuilt the test kernel to add netconsole support, and I have not been able to trigger the problem since. It wouldn't be at all suprising to find out that this bug lies not in the filesystem code but somewhere lower, such as the block layer or even the SCSI core. It seems to have a large random component as well as a delayed impact. Rocko is able to trigger it a lot more reproducibly. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
