I don't think they are the same issue. The previous one hasn't been solved yet, but it occurred with 2.6.26 and you are using .27-rc1. > [ 577.639420] Mesh plink with 00:19:e0:86:0f:2f ESTABLISHED > [ 602.864544] BUG: sleeping function called from invalid context at > mm/slab.c:3043 > [ 602.869975] in_atomic():1, irqs_disabled():0 > [ 602.874241] INFO: lockdep is turned off. > [ 602.878162] Pid: 5160, comm: ath5k_pci Not tainted > 2.6.27-rc1-wl-14922-gb73da91 #4 > [ 602.885719] [<c0172e5f>] kmem_cache_alloc+0xef/0x110 > [ 602.890794] [<c04e9908>] mesh_path_add+0xb8/0x2f0 > [ 602.895610] [<c04e9908>] mesh_path_add+0xb8/0x2f0 > [ 602.900468] [<c04eb8c6>] hwmp_route_info_get+0x406/0x4c0 > [ 602.905886] [<c04eb4e5>] hwmp_route_info_get+0x25/0x4c0 > [ 602.911927] [<c04eb9f4>] mesh_rx_path_sel_frame+0x74/0x870 > [ 602.917257] [<c04d76dd>] ieee80211_rx_bss_info+0x67d/0xe80 > [ 602.922846] [<c04d70dc>] ieee80211_rx_bss_info+0x7c/0xe80 > [ 602.928353] [<c04d9d40>] ieee80211_rx_mgmt_action+0x180/0x8a0 I guess mesh_path_add should be using GFP_ATOMIC instead of GFP_KERNEL, since it's called under rcu_read_lock?
