kernel 3.2.2 breaks intel centrino wireless
Last modified: 2012-02-01 12:22:30 EST
Description of problem:
I have a Samsung netbook with built in wireless:
09:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 05)
Subsystem: Samsung Electronics Co Ltd Device c0a8
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx+
Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR+ <PERR- INTx-
Latency: 0, Cache Line Size: 32 bytes
Interrupt: pin A routed to IRQ 46
Region 0: I/O ports at 2000 [size=256]
Region 2: Memory at f050c000 (64-bit, prefetchable) [size=4K]
Region 4: Memory at f0508000 (64-bit, prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: r8169
Kernel modules: r8169
With kernel 3.2.2 wireless associates with an AP just fine, but after a few seconds to a few minutes the connection drops. NetworkManager still thinks the link is up, nothing appears in dmesg, but the link is dead. Restarting NetworkManager.service restarts the connection, but after a few seconds it dies again in the same way. Reverting to kernel 3.1.6-1 fixes the problem.
Version-Release number of selected component (if applicable):
That lspci info is for an ethernet card. :-) Can you attach the full lspci (or 'lspci -n') output?

Not enough coffee, sorry. It's a:
05:00.0 Network controller: Intel Corporation Centrino Wireless-N 130 (rev 34)
so, iwlwifi and friends.
OK, this now looks like a duplicate of BZ 785239, closing as such.
