As shown in the dmesg output, this is likely the firmware problem, and Intel won't provide the new firmware for old chips. While we should report this again to the upstream bug tracker (bugzilla.kernel.org), you may try some iwlwifi module options that are related with the power management. Also, downgrading the firmware might be worth to try, too. It's iwlwifi-6000g2a, and currently iwlwifi-6000g2a-6.ucode is used. So try to remove /lib/firmware/iwlwifi-6000g2a-6.ucode (or ucode.xz) file and reboot. (Maybe safer to move to another place or rename the file instead of removing it, so that you can recover later, too). -- You are receiving this mail because: You are the assignee for the bug.

As for power management tweaks, I also suspected that could be a factor, as I use TLP which includes pretty aggressive power management tweaks across the board. Would you recommend anything in particular? I've seen recommendations for:

...

options iwlwifi 11n_disable=1 swcrypto=0 power_save=0 #also: 11n_disable=8 options iwlmvm power_scheme=1 options iwlwifi uapsd_disable=1

As well as:

...

options iwlwifi swcrypto=0 options iwlwifi power_save=0 options iwlmvm power_scheme=1 options iwlwifi uapsd_disable=1

Or simply:

...

options iwlwifi power_save=0

I'm not sure about the 11n_disable option codes or if that has anything to do with this?

Honestly speaking, I have no idea what really matters. I would try the bottom line first, i.e. disable all suspicious ones.

There are indeed quite a few reports of this on bugzilla.kernel.org, should I add on to an existing report or open a new one? - https://bugzilla.kernel.org/show_bug.cgi?id=207409 - https://bugzilla.kernel.org/show_bug.cgi?id=205387 - https://bugzilla.kernel.org/show_bug.cgi?id=208425

It's fine to create a new report unless you find the exactly same bug with the same hardware (Lenovo T530). You can join to other bugs meanwhile, and close yours later as a duplicate. -- You are receiving this mail because: You are the assignee for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=1179971 http://bugzilla.opensuse.org/show_bug.cgi?id=1179971#c7 --- Comment #7 from S. B. --- I seem to have fixed that particular error with the following in /etc/modprobe.d/iwlwifi.conf

options iwlwifi bt_coex_active=0 swcrypto=1 11n_disable=8

It appears that the issue was also being complicated by some wireless interference causing "extensive data loss" errors in RouterOS, but I managed to switch to a more free channel. -- You are receiving this mail because: You are the assignee for the bug.

I am connected on 5Ghz (the issue before only appeared on this band), I have removed all iwlwifi options from modprobe and I have not seen any errors in a while, where before I'd suffer them every one or two minutes. The last kernel release has indeed included fixes to iwlwifi: https://lwn.net/Articles/846116/ -- You are receiving this mail because: You are the assignee for the bug.

I'm going to be trying the opposite of what you did. I disabled my iwlwifi.conf tweak from comment #7 , and I'm now using a new Mikrotik router with a 5Ghz network, whereas when I opened this bug report I was having major issues with my only 2.4Ghz network. I'll report back if anything gets better or worse, but this bug is frustratingly random as you've noted. -- You are receiving this mail because: You are the assignee for the bug.
