Hallo,
I just got the 2.6.0 kernel running (without major problems). The only annoying issue I have is the tg3 network driver. Sending out a 100 MBit/s stream is no problem. Receiving with this speed makes the system a bit unresponsive. This means the mouse (usb) freezes now and then for a short period and the system monitor applets from gnome hanging at the same time too. There are no system messages that indicate any error. With 2.4.x I used the original driver from Broadcom (http://www.broadcom.com/drivers/downloaddrivers.php) that worked without any problem. The tg3 driver in 2.4.23 caused a high system load on network traffic - maybe this problem is related. My system is a Pentium 4 @ 3GHz with Hyperthreading enabled - i.e. 2 logical processors. The mainboard (Epox 4PDA2+) has a bcm 5705 network chip:
02:01.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5705 Gigabit Ethernet (rev 01) Subsystem: Unknown device 1695:9013 Flags: bus master, 66Mhz, medium devsel, latency 32, IRQ 21 Memory at f8000000 (64-bit, non-prefetchable) [size=64K] Capabilities: [48] Power Management version 2 Capabilities: [50] Vital Product Data Capabilities: [58] Message Signalled Interrupts: 64bit+ Queue=0/3 Enable-
Is this issue known? Are there any fixes. Do you need more information?
Thanks, ron
