regression with new Nvidia driver (1.0.9631)

2006-12-08 Thread Yuri Khotyaintsev
I have upgraded x11/nvidia-driver to the latest port version (driver 
version 1.0.9631) and now my X refuses to start in 1600x1200 mode, I 
even tried with DefaultDepth 16. Reverting to the old driver (driver 
version 1.0.8776) restores the correct behavior.


I have :
nvidia0:  mem 
0xe800-0xebff,0xd800-0xdfff,0xee00-0xeeff irq 16 
at device 0.0 on pci1

NFS/TCP

Will a fix for NFS/TCP (nfs_socket.c rev 1.138) be ever committed to stable?

mohan committed a fix for one such problem a few days ago.  It will
not be in 6.1-RELEASE, but you should be able to apply the patch
yourself.  It would be nice to know how it works for you.

I have patched nfs_socket.c on all clients and run the same kind of processing 
which was causing the problem. I can report that the problem is gone with 
nfs_socket.c rev 1.139. I only got one "nfs send error 35" on one of the 
clients instead of hundreds of messages I was seeing before. Thank you very 
much!

BTW, what is better/faster TCP or UDP for running NFS between hosts connected 
to the same gigabit switch?

NFS/TCP problems

2006-05-08 Thread Yuri Khotyaintsev
I have an NSF server and several clients which write large text files to the 
server. All machines are running max one week old STABLE and are connected to 
the same gigabit switch, and have identical nics (em). Amd mount options are:
/defaults

Almost all the time I get the following messages on the server:

And corresponding messages on a client:

Here are the two panics which I got with INVARIANTS and WITNESS enabled.

I am compiling a new kernel with INVARIANTS and WITNESS now. Will wait for a 
"better" panic ;-)

Fatal trap 12: page fault while in kernel mode

2005-12-02 Thread Yuri Khotyaintsev
I have the following panic occurring several times a week. The machine is an 
NFS server, and it usually panics early in the morning, when first people try 
to access it. After reboot it may work OK for 1-2 days, and then panics 
again. I have tried changing memory and replacing disk which was exported via 
NFS, but nothing helped :(

Any suggestion on how to fix this panic will be very much appreciated !
