When I mount manually an ext3 linux partition under FreeBSD 5.2 with mount -t ext2fs /dev/ad0s6 /mnt (for example) when I get out of FreeBSD with Ctrl Alt Supp, the ext2 partition still mounted, I get the message Syncing disk buffers remaining 1 1 1 1 1 ... giving up on 1 buffers At the next boot of FreeBSD, I have the message : / was not properly dismounted For Slackware at boot an fsck occurs for the partition. When I add the option -r (read only) the situation is the same for FreeBSD. For Slackware everything is OK >How-To-Repeat: The problem seems completely repeatable. >Fix: First of all to unmount before getting out ! of course. Second. On the same machine I have too a 5.1 freeBSD copy. I have tried the same problem. There is really no problem at all. Everything is OK for 5.1 and Slackware. for 5.1 and 5.2 I have recompiled the kernel with the same file except the name. Here is the output of uname -a for 5.1 : FreeBSD P3.michel.fr 5.1-RELEASE FreeBSD 5.1-RELEASE #0: Fri Jun 13 22:27:47 CEST 2003 root@P3BSD.michel.fr:/usr/src/sys/i386/compile/NOYAU-P3-5.1a i386 Third. There are some files modified between 5.1 and 5.2 in /usr/src/sys/gnu/ext2fs alpha-bitops.h has disappeared in 5.2, ext2_bitops.h has appeared. ext2_bmap.c ext2_inode.c ext2_linux_balloc.c ext2_linux_ialloc.c ext2_vfsops.c ext2_vnops.c fs.h are modified in 5.2. I know too little of the problem to go farther. >Release-Note: >Audit-Trail: >Unformatted:
