 |
|
Hi
This is bugging me for quite a while now...
Local Network speeds are fine(3-4MByte/s over a 100Mbit switch) connections to other sites http/ftp(gentoo mirror: mirror.switch.ch for example) is very slow usualy below 4kByte/s.
On my other machines I have 200kByte and faster to the same server so it isn't my internet connection.
I have a Dell Inspiron 9300 laptop with a Broadcom ethernet chip:
| Code: |
0000:03:00.0 Ethernet controller: Broadcom Corporation BCM4401-B0 100Base-TX (rev 02)
|
I am using the default b44 module with latest gentoo sources kernel.
I have acpi=noirq added to my kernel boot commandline otherwise the network doesn't work at all.
ACPI is on the same interrupt as eth0:
| Code: |
# cat /proc/interrupts
CPU0
0: 1694227 XT-PIC timer
1: 7095 XT-PIC i8042
2: 0 XT-PIC cascade
9: 32405 XT-PIC acpi, eth0
11: 1187 XT-PIC Intel ICH6
12: 55889 XT-PIC i8042
14: 16675 XT-PIC libata
15: 17 XT-PIC libata
NMI: 0
ERR: 0
|
I can't see anything unusual in the kernel log that gives a hint on what could be the problem.
| Code: |
# dmesg|grep b44
b44.c:v0.95 (Aug 3, 2004)
b44: eth0: Link is down.
b44: eth0: Link is up at 100 Mbps, full duplex.
b44: eth0: Flow control is off for TX and off for RX.
|
Pinging shows me a delay of a few ms seconds, no packetloss (64Byte Pings)
Does anyone have an idea what could be causing this? |

| You could try a vanilla-sources kernel, perhaps 2.6.13-rc3. I'm not sure if it'll help, but it's worth a shot. |

I have the same laptop - haven't tested network transfer speeds, but it sure takes a long time to get a DHCP address and often comes up with a reset error message
I'm using vanilla 2.6.12.2

Wow.. this exactly what I'm going through now. Did you resolve this????
https://forums.gentoo.org/viewtopic-t-484322-highlight-hanji.html
My eth0 is on a different interrupt than ACPI.. nothing is on the eth0 interrupt. I'm also using similar boot options (acpi=noirq ro acpi=off). I also disabled acpi in the kernel for now.. think that might help no dice. All I know is that LiveCD makes the nic work fine.
I have a Dell Inspiron E1505 using gentoo-sources-2.6.17-r4
Any help is greatly appreciated!!!!
Thanks

| I've had similar problems with my laptop with b44 which I first though was a window scaling problem (https://forums.gentoo.org/viewtopic-t-475756-highlight-mtu.html). But it did no good. I was using latest gentoo sources (2.6.17-r4). Reverting to 2.6.15-r1 did the trick, so you could try out that? |

Hello
Rolling back to 2.6.16-gentoo-r12 fixed me up... so it's 2.6.17 deal. Bummer.
Thanks for your suggestion!!!!
