[Madwifi-users] madwifi conflict with linux-2.6 and ACPI

[Philippe <phi...@gc...>]

Problem with Madwifi on Linux 2.6 with ACPI compiled in.

System:=20
Laptop Compaq Presario 1700T / Gentoo Linux 2004.1 + some updates
Wireless: Proxim Orinoco 11b/g PC Card (Model 8471-WD)
kernel: gentoo-dev-sources-2.6.5-r1
madwifi from portage: madwifi-drivers-0.1_pre20040514 (ath_hal 0.9.8.6,=20
wlan 0.7.3.1 BETA, ath_pci 0.8.5.5 BETA, Chipset ID'ed as Atheros 5212)

Description:
When the card is inserted, the events/0 process uses up to 99% of CPU=20
time as reported by top. Card is assigned IP via DHCP and I can ping=20
other computers. But, the system is too slow to be usable.

With a kernel compiled with ACPI off, the card works.

I haven't tried it with a gentoo-sources 2.4 kernel.

However, I tried Knoppix 3.4 today. It defaults to a 2.4 kernel which=20
does use ACPI. The card works normally. But with the 2.6 kernel, I get=20
the same behavior as my gentoo 2.6 kernel.

If anyone has a clue.....

TIA
