Red Hat Bugzilla – Bug 186526
Very slow network with tulip driver
Last modified: 2007-11-30 17:11:28 EST
Description of problem:
Terrible network performance on tulip-based network card. Can't get above about
30k/s transfers on an unloaded 100Mbit LAN.
Version-Release number of selected component (if applicable):
Substituting kernel 2.6.15-1.1833_FC4smp solves the problem.
lspci info for the card:
00:0d.0 Ethernet controller: Lite-On Communications Inc LNE100TX (rev 20)
Subsystem: Lite-On Communications Inc LNE100TX
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr-
Stepping- SERR+ FastB2B-
Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort-
<TAbort- <MAbort- >SERR- <PERR-
Interrupt: pin A routed to IRQ 4
Region 0: I/O ports at e800 [size=256]
Region 1: Memory at febfdf00 (32-bit, non-prefetchable) [size=256]
Expansion ROM at feb80000 [disabled] [size=256K]
Is this still a problem w/ current FC5 kernels?
If so, please try the FC5.netdev kernels:
Does the issue still occur with the FC5.netdev kernels?
Yes, it is. I've been using 2.6.16-1.2069_FC4.netdev.13smp for a while, and
while the machine acts normally at boot, the problem shows up again after some
time has passed, usually a week or two, sometimes a few days. Once it does start
up, a soft reboot is not sufficient -- the machine needs to be power-cycled.
I am currently installing 2.6.16-1.2122.2.3_FC5.netdev.3 (smp), and will report
if I experience any more problem.s
Optimistically presuming that the lack of further complaint indicates
improvement of the situation... :-)
