Help with filing a [maybe] ZFS/mmap bug.
Hi All, I have what I think is a ZFS related bug. Unfortunately my simplest test case is a bit cumbersome and I haven't definitively proven that the problem is ZFS related. I'm hoping for some feedback on how to move forward. Quick background: I rip my CD's using grip and produce flac files. I tag the music using Musicbrainz' Picard and transcode it to mp3's within Picard

[PATCH] Locking for adv(4), adw(4), aha(4), ahb(4), aic(4), and bt(4)
I have patches to add locking to the adv(4), adw(4), aha(4), ahb(4), aic(4), and bt(4) drivers so that they no longer use Giant. I would appreciate any testing folks are able to do. The patches are against HEAD but should apply to 8 or 9. Make sure you have INVARIANTS and INVARIANT_SUPPORT enabled for any initial testing that you do. Thanks! http://www.FreeBSD.org/~jhb/patches/adv_locking.patch http://www.FreeBSD.org/~jhb/patches/adw_locking.patch http://www.FreeBSD.org/~jhb/patches/aha_locking.patch http://www.FreeBSD.org/~jhb/patches/ahb_locking.patch http://www.FreeBSD.org/~jhb...

wpi driver freeze on boot
I've got a HP dv8000 laptop. Setting up the wpi driver for wireless freezes the system on boot with the following error: wpi0 requested unsupported memory range wpi0: could not allocate memory resource It lists a pcbi device (pcbi4 i think) and an actual memory range, but since I have to reboot using kernel.old the /var/run/dmesg.boot is wiped with the info. Is there anyway to grab the

gmirror(8) and graid3(8) changes.
...ftc synchronization from the topology lock to per-device sx lock. I'd like to ask gmirror/graid3 users to test those patches as much as possible, because I want to commit them to the HEAD and RELENG_6 branches. Because of locking changes it will be really good if you can turn on INVARIANTS, INVARIANT_SUPPORT options and eventually DIAGNOSTIC in your kernel.

The broadband will be a T3 with failover to

fsck_ufs locked in snaplk
Colleagues, one of my servers had to be rebooted uncleanly and then I have backgrounded fsck locked for more than an our in snaplk: 742 root 1 -4 4 1320K 688K snaplk 0:02 0.00% fsck_ufs File system in question is 200G gmirror on SATA. Usually making a snapshot (e.g., for making dumps) consumes 3-4 minutes for that fs, so it seems to me that filesystem is in a deadlock. Any

Lots of overhead with ZFS - what am I doing wrong?
I was trying to simply test bandwidth that Solaris/ZFS (Nevada b63) can deliver from a drive, and doing this: dd if=(raw disk) of=/dev/null gives me around 80MB/s, while dd if=(file on ZFS) of=/dev/null gives me only 35MB/s!?. I am getting basically the same result whether it is single zfs drive, mirror or a stripe (I am testing with two Seagate 7200.10 320G drives hanging off the same interface
