Description:

Full system lock-ups (hang-ups) -> ie -> no caps/num lock functioning, no keyboard functioning, no mouse movements, or software resets, occur almost every time when there is increased network (ethernet) activity over nfs v3.

This has been happening for a week, after the following upgrade:
[2011-03-16 17:29] upgraded kernel26 (2.6.37.3-1 -> 2.6.37.4-1)
[2011-03-16 17:29] upgraded kernel26-headers (2.6.37.3-1 -> 2.6.37.4-1)

Additional info:
* package version(s)
2.6.37.4-1

* config and/or log files etc.
Pacman logs of the update:
[2011-03-16 17:29] upgraded kernel26 (2.6.37.3-1 -> 2.6.37.4-1)
[2011-03-16 17:29] upgraded kernel26-headers (2.6.37.3-1 -> 2.6.37.4-1)

After these, either a system hang-up, or a software reset occured, because the exact next entries where:

Mar 20 23:16:26 machine kernel: Command line: root=/dev/sda2 ro 5 swncq=1 nomodset
Mar 20 23:16:26 machine kernel: BIOS-provided physical RAM map:

Steps to reproduce:
Do any heavy ethernet usage over nfs v3 network shares.
For example, locally, copy files, or untar files, <source> -> <dest>, with both <source> and <dest> being on a remote over-nfs location.
It will happen sooner than later.

Even more data:

1. Before the kernel update, there was not a single instance like these:
Mar 20 19:13:25 machine kernel: NOHZ: local_softirq_pending 08
Mar 20 23:15:24 machine kernel: net_ratelimit: XX callbacks suppressed
in the kernel logs.

2. The first entry of such errors in the logs happened on:

just after pacman log indicates the kernel update.

[2011-03-16 17:29] upgraded kernel26 (2.6.37.3-1 -> 2.6.37.4-1)
[2011-03-16 17:29] upgraded kernel26-headers (2.6.37.3-1 -> 2.6.37.4-1)

3. Ethernet chipset is this one:

Mar 20 19:12:08 machine kernel: r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded
Mar 20 19:12:08 machine kernel: r8169 0000:04:00.0: PCI INT A -> GSI 18 (level, low) -> IRQ 18
Mar 20 19:12:08 machine kernel: r8169 0000:04:00.0: setting latency timer to 64

4. I have rolled-back kernel26 (and headers) to 2.6.37.3-1 and put them in Ignorepkg in pacman.conf.

After kernel downgrade/rollback, there have been 24 continuous hours of the usual heavy ethernet usage, with no further incident at all, and completely normal-flawless behavior.

So kernel26 2.6.37.3-1 behaves flawlessly.

5. Initial report and investigation of this, is described in this thread:

Additional comments about closing:  linux 3.0 had a driver rewrite that fixed it for my realtek card.

Problem remains in 2.6.37.5.

After upgrading:

[2011-03-26 16:10] upgraded kernel26 (2.6.37.3-1 -> 2.6.37.5-1)
[2011-03-26 16:10] upgraded kernel26-headers (2.6.37.3-1 -> 2.6.37.5-1)

Here was the first lockup:
