Subject: [2.6.8.1]Oops on eject /mnt/cdrom
Date: Mon, 18 Oct 2004 17:41:30 +0900 [thread overview]
Message-ID: <ckvvjr$hev$1@sea.gmane.org> (raw)
Yes this is 2.6.8.1, changed the version to agrre with x.y.z :-(
No patches, vanilla.
I did `mount /mnt/cdrom` and mounted a CD-R with some HTML/JPG data and looked through it (with Mozilla).
Then tried `eject /mnt/cdrom` and the command hang, so I checked dmesg:
ISO 9660 Extensions: Microsoft Joliet Level 3
ISOFS: changing to secondary root
Unable to handle kernel paging request at virtual address bb726bfc
printing eip:
c0151ff7
....
Runnig it through ksymoops gives:
ksymoops 2.4.9 on i686 2.6.8-KK1_sata. Options used
-V (default)

-l /proc/modules (default)

Warning (read_ksyms): no kernel symbols in ksyms, is /proc/kallsyms a valid ksyms file?

I tried to reproduce the oops, but to no avail till now. It may be the CD-R as it is a bit "strange", I have my CT scans from the hospital in DICOM format (+jpg) :-(
