-Subject: [PATCH] ath5k: fix spontaneus AR5312 freezes
-
-Sometimes while CPU have some load and ath5k doing the wireless
-interface reset the whole WiSoC completely freezes. Set of tests shows
-that using atomic delay function while we wait interface reset helps to
-avoid such freezes.
-
-The easiest way to reproduce this issue: create a station interface,
-start continous scan with wpa_supplicant and load CPU by something. Or
-just create multiple station interfaces and put them all in continous
-scan.
-
-This patch partially reverts the commit 1846ac3dbec0 ("ath5k: Use
-usleep_range where possible"), which replaces initial udelay()
-by usleep_range().
-
-I do not know actual source of this issue, but all looks like that HW
-freeze is caused by transaction on internal SoC bus, while wireless
-block is in reset state.
-
-Also I should note that I do not know how many chips are affected, but I
-did not see this issue with chips, other than AR5312.
