Description of problem:
System freezes completely when working with network (mounting nfs/smb
filesystems or working from xdm session from remote NCD)
Steps to Reproduce:
1. Boot the system
2. login with KDE session
3. mount smb network drive (from NT server)
4. Copy some files from/to smb drive
Actual Results: System freezes completely - mouse pointer not moves,
keyboard not responses (pressing <Num Lock> not leds).
telnet/ftp/xdm not accepts login from network
I have upgraded from Red Hat 6.1 to 7.1.
Updated all available packages in updates site.
My considuration that the kernel is source of the problem is based on
temporary solution I found:
Installing rpm of old kernel-2.2.14-5.0 and configuring lilo to boot the
old and the new one. With old kernel system works fine and stable.
Ok. What networkcard do you have ?
Could you give me the output of "lspci -v", this will give me more information
about what your system is.
I have also seen the kernel crash this way with smbmounts. I am not using xdm
and can therefore not comment on that. This has appened with kernel 2.2.16-22,
kernel 2.4.2-2 and now 2.4.3-2.14.14. lspci -v info attached below.

firstname.lastname@example.org: are you using the nvidia module by chance ?
Yes, I am (version 0.9-769). Is this a know problem then? My has otherwise been
stable, although just yesterday I discovered running wine/winamp (on remote
display, X not started) or java (j2v1.30) completely freezes my machine. I am
using 2.4.3-2.14.14 as found on rawhide.
Using the propriatry NVidia driver causes a lot of problems; it seems they
overwrite random bits of kernelmemory. Please take any bugreports while having
the driver loaded (or having unloaded the driver but not rebooted) to NVidia,

On same machine hardware and configuration
(server for: xdm,nfs,samba,news,http,pop3,bootp,dns)
was running stable without freezes or crashes for months RedHat 5.2, 6.1
and now 7.1 - just with older (from 6.2 system) kernel.
When I ran wine/winamp I did exactly that, i.e. not having started the nvidia
driver ever since boot. The kernel crashed without the nvidia module ever having
been loaded (X/nv not running). The wine/winamp combo caused the crash.
wine/winamp worked completely normal until the kernel crashed (with no console
output what so ever. Sudden death I would call it). I tried with the builtin
ymfpci/ac97_codec module as well as the alsasound system. xmms nor mpg123 caused

Running version 7.1 on a x686 platform we've also seen exactly the same
symptoms although we aren't really accessing an smb drive but rather a 7.0
RedHat system with NFS directories exported. At some point after first
accessing the NFS mounts the system freezes (no mouse/cursor operation
possible) although telnet appears to connect but never gets to the login
prompt. Pings do work but any other form of network access fails (ftp, rsh,
I have seen very similar freezes on my system running RH7.1 on i686 (PIII800)
even in console mode (just booted), all apparently when other hosts start SMB
connections & transfers. The system freezes completely without any log and no
other solution than resetting...
Try the 2.4.3-12 updated kernel, WITHOUT the nvidia driver
The freezes seem to be appeared exactly with the new 2.4 kernels.
I use the last 2.4.3-12 update recompiled just with modules I need
(no nvidia driver, but Matrox G450).

I just have updated all available rpms from redhat including the kernel rpm and
problem disappears on both machines.
I downgraded to the standard 2.4.2-2 (RH7.1 original) kernel and the problem
seems to be disappeared.
All the problems seems to be resolved (almost for me) with the most recent "stable" kernel versions (2.4.5 / 2.4.6).
