I've been in contact with Mykola Dzham quite some time now and we are trying to figure out a resume issue on his iwn(4) device. It does seem that this device does not come up correctly after suspend. The interesting part is, that even pciconf -l -bcv ist not able to get all information. Before suspend: iwn0@pci0:6:0:0: class=0x028000 card=0x13018086 chip=0x42328086 rev=0x00 hdr=0x00 vendor = 'Intel Corporation' device = 'Carte Intel WiFi Link 5100 AGN (Intel WiFi Link 5100)' class = network bar [10] = type Memory, range 64, base 0xec800000, size 8192, enabled cap 01[c8] = powerspec 3 supports D0 D3 current D0 cap 05[d0] = MSI supports 1 message, 64 bit enabled with 1 message cap 10[e0] = PCI-Express 1 endpoint max data 128(128) link x1(x1) After resume: iwn0@pci0:6:0:0: class=0x028000 card=0x13018086 chip=0x42328086 rev=0x00 hdr=0x00 vendor = 'Intel Corporation' device = 'Carte Intel WiFi Link 5100 AGN (Intel WiFi Link 5100)' class = network Note the last 4 missing lines. After a bit of searching i stumbled across kern/136876 which described a very similar (same?) issue for a bge(4) device. The question now is, might there be any special "power management" feature which prevents proper resume? How might a solution look like? Thanks. -- Bernhard
