Hello,
I get a repeatable panic when trying to cpy files from an ext3 filesystewm
which is mounted read-only. Listing files works ok.
Details:
root@kg-u35jc# uname -a
FreeBSD kg-u35jc.kg4.no 10.1-STABLE FreeBSD 10.1-STABLE #0 r283269: Fri May 22
09:14:57 CEST 2015
[email protected]:/usr/obj/usr/src/sys/GENERIC amd64
Steps to reproduce:
# kldload ext2fs
# mount -r -t ext2fs /dev/ada0s5 /mnt
# cp /mnt/whatever-file <somedir>
Results in a nice panic:
root@kg-u35jc# cat /var/crash/info.0
Dump header from device /dev/ada0s3b
Architecture: amd64
Architecture Version: 2
Dump Length: 1075154944B (1025 MB)

Hostname: kg-u35jc.kg4.no

which is easy to reproduce:
root@kg-u35jc# cat /var/crash/info.1

Is this a known problem ( I tried searching, but didn't find anything), or
should I put it into Bugzilla?
(core.txt.[01] are available, but largish at over 200K each, so I didn't try to
get the mailing list to accept them)
