I do have Netatalk running mind you but it's rarely used. The problem only ever happens under disc load when I do a 'portsdb -Uu' command. I never used to get the problem but I can't quite recall when it started. It was definately after upgrading to 4.4 and to UDMA-100.

I am. But there's absolutely no load. This is my workstation at home. The only other box is the firewall - FreeBSD of course. I tend to have copies of everything I need at work. For the docs and trial runs. I notice that my network card shares an irq with my SB128. How did that happen? I'll fix this. I've had no crashes last 24 hours, but I thought I'd fixed it once before. > > -- > Bob <[EMAIL PROTECTED]> | Please don't spill hot things on Bob. > > To Unsubscribe: send mail to [EMAIL PROTECTED] > with "unsubscribe freebsd-stable" in the body of the message -- ian j hart To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-stable" in the body of the message

I dont have exactly the same problem but I am running samba. Stable cvsuped today (12/12/01) crashes on an SMP machine. Thing is, it's disks are SCSI.

Re: 4.4-STABLE crashes - suspects new ata-driver over wd-driver
FWIW, I moved from 4.3-R to 4.4-Stable a day or so ago, because I was seeing the ata0 timeout, resetting, plus experiencing random crashes under virtually no load, but always after cron ran at 0200. So far, (only one day and night) no problems anywhere. Cleanly built from cvcsup on 11 Dec. System is Athalon 880, and does have samba running on it.

Re: 4.4-STABLE crashes - suspects new ata-driver over wd-driver
Here's another "me too". My box just froze when copying a large amount of big files over the network to my machine, causing heavy disc access and lots of interrupts. Curiously I just updated my box to 4.4-STABLE from 4.3-RELEASE and it hasn't occured before. Though in my case the box is quite old (dmesg attached) but is using a relatively new IDE disc. -Richard Copyright (c) 1992-2001 The FreeBSD Project.

I don't have the specs handy since I'm at work, but I am using IDE drives. The trouble started last week, using a 4.4-STABLE kernel built on Nov 3. I reinstalled world yesterday from the latest 4.4-STABLE, and it hasn't gotten better. For me, it only happens during heavy disk access, such as when backing up my hard drive to a huge tar file, or when doing build or clean. My machine will either lock up or reboot.

Re: 4.4-STABLE crashes - suspects new ata-driver over wd-driver
I seem to have the same problem... when my IDE drive is under heavy use the
whole computer goes down. :( It's my server so it's very serious. My root
partition is a SCSI drive.. the IDE drive is only used for ports... and the
computer often shuts down when I run the command "portsdb -uU"... (heavy
disk usage)
