Hi,
I hope this is the correct list for an issue like that, if not, a pointer
would be appreciated.
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.
