Hi,
I've done another reboot, took ages to get past starting the cups server (which it eventually did), but looking in var/log/messages, I saw this.

Other processes killed include such favourites as modprobe (and that's it - though it was killed 8 times!).
Is this related to cups and if not, where is it from as I think it should be in bugzilla rather than my desktop.
Something *is* up with cups though. If I try to use system-config- printer, the entire machine locks up, lots of HD thrashing and no action. I have to switch the machine off to get things working again.
Very annoying!

You want to find out if its cups? turn off the cups service and reboot again and examine the log for similar messages. Isolate what causes the problem if you can by turning off services one at a time.
As a counter-point I just booted into the 533smp kernel and I'm not seeing any problems with cups. I'm using a usb hp 3650 printer.

Are you sure its cups? and not something hardware specific that cups just happens to set off? I can start the system-config-printer dialog without the cups service running.

cups worked yesterday on the 2.6.8-1.503 kernel and not today under the 532 kernel. I have done a cups shutdown and then restart. Massive lag, lots of HD thrashing then everything died and I needed a power reset to get back to normal.
On boot, took ages to get past the cups start up.
I've done an update to the 533 kernel and will see what that does.
I still suspect a problem with cups.

Going to 533 made no difference, big delays in boot up.
Looking harder this time, I can start system-config-printer, but when I try to edit the printer, that's when the disk thrashing starts. Any way of tracing if it's cups gone mad?

not to beat a dead horse... but i can edit my printer definition via system-config-printer without the cups service running. The cups service doesnt get started till i hit the apply button.
Try stopping the cups service... make sure everything looks okay with cups stopped then run s-c-printer and edit the entry... see if it thrashes before you hit apply... if it thrashes see if the cups process was restarted...

Been there, seen it, done it, got the 2.1Mb strace generated file, kernel panic and lock up.
It's not right I tellls ye!

Do you have "rhgb quiet" at the end of the kernel line in grub.conf? If so, try booting with that removed. I was hanging at the cups startup during boot until I removed that.

Hi,

Nope. I have it removed while using rawhide - so I can try and find where problems are.
If so, try booting with that removed. I was hanging at the cups startup during boot until I removed that.
Nope. It was still hanging with plenty of problems which seemed to be nscd related (probably symptomatic rather than actual cause).

Condolences on this miserable problem.
I would be thinking about lsof -n before and during the thrashing. For example
# lsof -n >temp # (perform thrashing) # lsof -n >temp1 && diff temp temp1 | grep -v lsof
I just tried it here with just a pause and got no changes in open files, so there is some hope you might see interesting and relevant changes...

Can't see anything much in that. However, /var/log/cups/error_log is showing something of interest...

(this was repeated quite a few times before this snippet)
Definately looks like a cups problem.
A previous error_log gave this
