Reinette,
This info comes from an openSUSE 11.3 M4 bug report at
https://bugzilla.novell.com/show_bug.cgi?id=592399
The kernel is 2.6.33 with openSUSE patches, but none of them should touch iwlagn.
The lspci info for this card is:
04:00.0 Network controller: Intel Corporation Ultimate N WiFi Link 5300
Subsystem: Intel Corporation Device 1121
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: 64 bytes
Interrupt: pin A routed to IRQ 31
Region 0: Memory at f8000000 (64-bit, non-prefetchable) [size=8K]
Capabilities: <access denied>
Kernel driver in use: iwlagn
His problem is that the wireless keeps getting a microcode error and is dropping
and remaking the connection about every 40 seconds. It logs the following:

Have there been changes that would have fixed this problem, or is this a known
regression? The OP (Cc'd here) reports that it works better on 11.1 (a 2.6.27
kernel) and 11.2 (a 2.6.31 kernel) than it does with this 2.6.33 kernel.
Thanks,
Larry

This is the firmware watchdog timer kicking in because something is
hanging in firmware or maybe just talking too long. Unfortunately quite
a few of these have been popping up recently, so far I have recorded six
bug reports with the same line number you are reporting here.
You could try the patches accompanying
https://bugzilla.kernel.org/show_bug.cgi?id=15374 ... that will not make
the firmware error go away, but should help with cleanup when it does
occur and hopefully enable the connection to recover without user
noticing ... although I am not sure about that if this error is hit so
often.

>From what I see in the git log for mainline 2.6.34, these patches are already
there. If that is correct, the OP's problem should go away as I think the next
Milestone release of openSUSE should switch to 2.6.34-rcX.
Thanks for the response.
