Subject: [ath9k-devel] AR9485 on acer one d257 disconnects and hangs very often (ath: Failed to stop TX DMA!)
Date: Mon, 26 Dec 2011 23:25:29 +0100 [thread overview]
Message-ID: <4EF8F459.2010606@gmail.com> (raw)
Hello,
I've bought a new Acer One D257 with AR9485 as wireless card, I run
Debian Squeeze and I can't find a way to use it.
In fact, very often the connection hangs and the wireless device becomes
totally frozen; there is nothing I can do to avoid reboot to make it
working again.
In dmesg output, I find lots of lines like these ones:
ath: Failed to stop TX DMA in 100 msec after killing last frame
ath: Failed to stop TX DMA!
ath: DMA failed to stop in 10 ms AR_CR=0xffffffff AR_DIAG_SW=0xffffffff
ath: Could not stop RX, we could be confusing the DMA engine when we start RX up
ath: Chip reset failed
ath: Unable to reset channel (2467 MHz), reset status -22
ath: Unable to set channel
ath: Failed to stop TX DMA in 100 msec after killing last frame
ath: Failed to stop TX DMA!
If I try to rmmod the aht9k module and insert it again, i find these lines:
ath9k Refused to change power state, currently in D3
ath: Couldn't reset chip
ath: Unable to initialize hardware; initialization status: -5
I've this problem with all these kernels:
- kernel 2.6.32 from Debian Squeeze
- kernel 2.6.39 from Debian Squeeze-Backports
- kernel 3.1.6 compiled by me from the source of kernel.org, with the
same config of original Debain 3.1 kernel
Disabling ipv6, bluetooth and nohwcrypt option in module has no effect.
Using wicd or network-manager is the same.
What else can I do?
Please give me some infos about it...
Thanks, Paolo
