USB system works incorrectly after kernel upgrade

usr345 · 11-03-2014, 05:25 PM

I have upgraded kernel to the latest one (3.18-rc2). And the USB system started to work incorrectly.

Speed of writing to the USB stick:

1. Old kernel: 9,4 Mb/s
2. New kernel: 540 Kb/s

On the old kernel my TP-Link TL-WN822N USB wifi adapter works. On the new - it doesn't. Here is the dmesg output, related to USB for both systems. On the old one you can see this line: "usb 1-2: ath9k_htc: USB layer initialized", missing on the new kernel.

Hi,

We miss a few information to help you, like the Linux distribution you use, the previous kernel version you used, the old and new config options...

PS at time of writing the mainline kernel is 3.18-rc3 and there have been changes in ath9k since 3.18-rc2.

metaschima · 11-03-2014, 06:26 PM

Did you change any options ?

For the USB speed double check this option:
Device Drivers -> USB support-> EHCI HCD (USB 2.0) support -> Improved Transaction Translator scheduling

For the wifi adapter, check the driver sub options if there are any.

Yes, this option is checked.

Wifi adapter driver is compiled, and can be loaded manually through modprobe. But the device doesn't start.

1. Linux distribution I use: Slackware 14.1

2. previous kernel version: 3.2.29-smp (shipped with Slackware by default)

3. New kernel: 3.18.0-rc2-smp+ (I don't know, why it became smp - I configured it to be compiled without SMP support).

What portion of kernel configs do I need to post? I got both of them. But they are so big, that I can't post everything here.

metaschima · 11-04-2014, 11:22 AM

How did you configure the new kernel ? Did you use 'make oldconfig' ? With this big of a version jump you should probably be checking every option. Either attach the configs or post the diff of them.

Didier Spaier · 11-04-2014, 12:13 PM

I'd add that Slackware 14.1 ships 3.10.17, not 3.2.29, that is included in Slackware 14, so I'm a bit puzzled.

To avoid the big jump that Metaschima rightly mentioned, you could take as a basis the kernel config shipped in /testing in Slackware-current, which is version 3.15.5 a time of writing and "make oldconfig" against that, copied in the kernel tree as /usr/src/linux-<version>/.config

The kernel became -smp because you didn't change the "local version" under General setup, as that is "-smp" in the Slackware kernel sources.

If I may add a bit of advice, and assuming that you just experiment compiling your custom kernel, that would be to begin with a -stable one, e.g. 3.17.2 at time of writing, unless you absolutely need something that is only shipped in mainline.

I used "make menuconfig". Files attached.

metaschima · 11-04-2014, 02:30 PM

Can you post the output of 'lspci -k' on the old and new system ?

Make sure to install the modules if you didn't.

Unfortunately, it became worse after it. I took the file config-generic-3.15.5.

Quote:

mv ./config-generic-3.15.5 /usr/src/linux/.config
make oldconfig
make menuconfig
make bzImage modules
make install_modules

Then put the modules and kernel to the appropriate dirs and ran lilo. Now I get kernel panic:

Quote:

Kernel panic - not syncing: VFS: unable to mount root fs on uknown-block(8,2)

Despite the fact, that ext4 fs module is compiled.

metaschima · 11-08-2014, 01:00 PM

ext4 should be built-in, not as a module.
