Re: [ATH] 9.2-PRERELEASE and wlan0 device disconnection
I am struggling with my AR9285 for more than a year now. Sometimes it is better, sometimes worse, but never without disconnections. I have also noticed it dies more frequently on heavy usage. I read somewhere that raising value of kern.ipc.nmbclusters (in my case to 51200) could be of help, so I am trying it at the moment. -- Marko Cupać ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org

A lot of the ath PRs filed by me can be closed. They're reminders that things needed fixing, which I've done. A lot of them are for older cards on older machines with odd behaviour due to PCI/cardbus issues, power save bugs, ACPI hilarity, etc. I've tried to port over some fixes to address these but it's hard to verify them without a (much larger) lab and (a lot more) free time to test it all.

Because I use jails and nullfs extensively, the nullfs enhancement demanded an increase in maxvodes, otherwise performance degraded, quite badly. Tripling the default suited my needs on 4GB systems, but I don't have an algorithmic recommendation; as for me it depends on the role/purpose of the server. If vnodes is an issue *and* you use mount_nullfs, another approach is to disable caching via mount_nullfs -o nocache as this may help to narrow the cause.

How would I make it into something like a giant floppy image that can be booted from syslinux or isolinux like the Super Grub Disk on the System Rescue CD? I could also try something by building grub2 from FreeBSD ports, don't know just what booting images I can create.

Elsukov Only difference in lsdev output was that the USB sticks didn't show, but that was because I had removed them. I reinserted the USB sticks, but they still didn't show, probably because the loader presumably does not recognize newly inserted USB sticks. I then typed reboot and successfully rebooted from the appropriate USB stick.

You're probably not talking to me, but headway here is slow. At our location, we have been continuing to test releng/9.2 extensively, but with r250907 reverted. Since reverting it solves the issue, and since there haven't been any further changes to releng/9.2 that might also resolve this issue, re-applying r250907 is perceived here as un-fixing a problem. Enthusiasm for doing so is correspondingly low, even if the purpose is to gather debugging info. :( However, after finally having clearance to test releng/9.2 r254540 with r250907 included and with DDB on five nodes. The problem cropped up in about an hour. Two threads in one process deadlocked, was perfect. Got it into DDB and saw the stack trace was scrolling off so there was no way to copy it by hand. Also, the machine's disk is smaller than physical RAM, so no dump file. :( Here's what is available so far: db show proc 33362 Process 33362 (httpd) at 0xcd225b50: state: NORMAL uid: 25000 gids: 25000 parent: pid 25104 at 0xc95f92d4 ABI: FreeBSD ELF32 arguments: /usr/local/libexec/httpd threads: 3 100405 D newnfs 0xc9b875e4 httpd 100393 D pgrbwt 0xc43a30c0 httpd 100755 S uwait 0xc84b7c80 httpd Not much to go on. :( Maybe these five can be configured with serial consoles.
