latest package madwifi-hal causes crashes and data corruption on Acer Aspire 150

Description

Running opensuse 11.0 and opensuse 11.1 on an Acer Aspire 150 gives issues with madwifi-hal-0.10.5.6 and older.

WPA-PSK is activated. Fixed IP-Adress. wpa_supplicant is in use, makes no difference whether the madwifi driver is used by wpa_supplicant or the wext driver is used by wpa_supplicant.

Phenomenon: when i.e. upgrading packages with Yast you get feedback about checksum mismatches. You can say repeat download once or twice, but then the system freezes. Things get worse if you activate the regular ethernet interface (even if you do not do anything with it) A different wireless device (i. e. ralink USB) works flawlessly. So it is not an issue of the onboard ethernet controller neither of it's driver but of the madwifi driver.

By the way: this is what dmesg outputs on my system:

ath_hal: module license 'Proprietary' taints kernel.

One more here: if you activate debugging and put ath_debug=255 into /etc/modprobe.d/ath you can fix the crashes - but this floods my /var/log/messages and reduces performance down by a factor of 4.

Hi folks, I finally found the issue and it is _not_ madwifi. In contrast, on Acer Aspire 150L with openSUSE (cannot tell about other distributions) the conjunction of r8169 as supplied with 2.6.27 (or 2.6.28, downgraded the driver, makes no difference) causes the problems. In contrast, when using the driver from Realtek (r8101) this problem is gone. So, it's not madwifi's fault, I will place the bug somewhere else.
