Subject: [ath9k-devel] ath9k: TX DMA, reset errors and 0xdeadbeef on not-so-hacked kernel.
Date: Mon, 15 Nov 2010 16:31:52 -0800 [thread overview]
Message-ID: <4CE1D0F8.70108@candelatech.com> (raw)
With the previously posted wpa_supplicant patch, I am able to reproduce
the ath9k DMA errors previously seen when I hacked the kernel
to share scan results.
The basic test: Create 30 STA interfaces, run one patched instance of
wpa_supplicant to manage all interfaces. My proprietary user-space app
is also running (gathering stats, etc). The system crashed within a few
minutes of starting the test.
The kernel does NOT have any significant changes, though it does have
this one applied:
mac80211: Fix deadlock in ieee80211_do_stop.
I cannot reproduce the problem with un-modified wpa_supplicant, so the error
is likely related to the speed at which interfaces attempt to associate.

Subject: ath9k: TX DMA, reset errors and 0xdeadbeef on not-so-hacked kernel.
Date: Mon, 15 Nov 2010 16:31:52 -0800 [thread overview]
Message-ID: <4CE1D0F8.70108@candelatech.com> (raw)
With the previously posted wpa_supplicant patch, I am able to reproduce
the ath9k DMA errors previously seen when I hacked the kernel
to share scan results.
The basic test: Create 30 STA interfaces, run one patched instance of
wpa_supplicant to manage all interfaces. My proprietary user-space app
is also running (gathering stats, etc). The system crashed within a few
minutes of starting the test.
The kernel does NOT have any significant changes, though it does have
this one applied:
mac80211: Fix deadlock in ieee80211_do_stop.
I cannot reproduce the problem with un-modified wpa_supplicant, so the error
is likely related to the speed at which interfaces attempt to associate.
