Hi All,
I just had "an issue" with my Linux 2.6.1 kernel. While working, I tried to rf -rf a directory, and was told my filesystem was mounted readonly (which it wasn't). I then shut the machine down, and on shutdown, I got a "kernel BUG at fs/ext3/super.c: 411". Full report below:
Mike
[1.] One line summary of the problem:
Filesystem became readonly, then kernel crashed on shutdown
[2.] Full description of the problem/report:
While working, I tried to rf -rf a directory, and was told my filesystem was mounted readonly (which it wasn't). I then shut the machine down, and on shutdown, I got a "kernel BUG at fs/ext3/super.c: 411".
bash-2.05b$ rm -rf ~/cxoffice/
rm: cannot remove `/home/mike/cxoffice//.manifest/cxoffice.xml': Read-only file system

[3.] Keywords (i.e., modules, networking, kernel):
ext3, slackware 9.1
[4.] Kernel version (from /proc/version):

I've removed the same directory many times, and the problem didn't happen before....

[7.6.] SCSI information (from /proc/scsi/scsi)
bash-2.05b# cat /proc/scsi/scsi Attached devices:
[7.7.] Other information that might be relevant to the problem
(please look in /proc and include all information that you
think to be relevant):My distro is slackware 9.1. I use the machine for work and play almost every day, so it had a few days uptime when the crash occured.
Looks as though the // in the path might be relevant... after rebooting the machine, I successfully removed the same directory.
I am a Wine developer and have done some limitted development with the Linux kernel before.
After a hard reset of the machine (after the crash), my /dev/hda2 partition that contains my home directory was full of errors. I wrote some of these down after running e2fsck manually.
This is the first time the problem has happened, so I'm dutifully reporting it :)
[X.] Other notes, patches, fixes, workarounds:
