Boot into single user mode 2. fsck / # finishes successful! 3. mount -u / 4. Do a few edits to files in /etc 5. mount -u -o ro / softdep_waitidle: Failed to flush worklist for 0xc1f36b30 mount: /dev/ad0s1a : Device busy I can't remount the root file system read-only, so I'm forced to type "reboot" and go to single-user mode again. At this point the root file system is dirty and fsck needs to be run to fix it. The same happens sometimes when going from multi-user to single-user ("shutdown now") and trying to unmount /usr. Sometimes it works, sometimes it fails the same way as above. Another thing I noticed: When remounting the root FS to read-only works, and I try to fsck it afterwards, I get this: ** /dev/ad0s1a (NO WRITE) So it refuses to fix anything, even though the FS is not mounted read-write. I'm not sure if this is expected behaviour, but it was my understanding that fsck should be able to fix file systems that are mounted read-only. All of that is with a recent 7-stable (20081016) on an ASUS notebook that works very well otherwise. Well, except that it's not supported by acpi_asus(4) even though the manpage claims it is, but that's probably unrelated to the softdep_waitidle problem.

"Transparent" proxies seem to vary from the distortions of a funhouse mirror to barely translucent. I really, really dislike them when trying to figure out the corrective lenses needed with each of them. -- R. Kevin Oberman, Network Engineer
