Re: Kernel panic -not syncing

@ukhippo

it's already done
I used for the first time a live cd and " chroot " to downgrade the kernel .
It was also a good time to install linux- lts ...

Thank you

Re: Kernel panic -not syncing

UKhippo - thanks again. I have the lts kernel in the cache. and had it installed, but had no entry for syslinux.

My instinct is to wait, but in an emergency I had load lts.

This is not my original post, so I will NOT mark it as SOLVED

Re: Kernel panic -not syncing

Attempted to upgrade to linux-4.1.4-1. Kernel panic persists.
Had to move back to linux-lts and nvidia-lts

Re: Kernel panic -not syncing

Same problem here on a AMD Phenom II X4 965 Processor.
I tried linux-4.1.4-1 but kernel panic persists.
I use 4.0.7-2 which works fine.

Re: Kernel panic -not syncing

Do the kernel people even know about this and are they working on a fix? Two or three upgrades to the kernel already happened with no fix, that's pretty pathetic on their end.

Do you have a link to the bug report you filed?

Re: Kernel panic -not syncing

To fix this, simply apply the patch. For more detail follow my initial bug report and my bisect project on that matter.

Re: Kernel panic -not syncing

I think I'm getting the same kernel panic, but it's showing up errors in my RAID array (resyncs and checks show no problems).

This is on an AMD 64 bit processor (but not a Phenom).

Re: Kernel panic -not syncing

Any news? What about linux 4.1.5-1? Has anybody tried it? Unfortunately I've no time for new troubles in these days

Re: Kernel panic -not syncing

Well, according to this link posted on the bug report (bug 101971), the fix might not be out until 4.3-rc1:

https://lists.manjaro.org/pipermail/man … 00579.html

Can anyone confirm?  Is archlinux going to apply the patch internally?  I'm not very familiar with how they handle this stuff

Re: Kernel panic -not syncing

Following the suggestion of philm, I copied the patch and looked for the ./drivers/base/cacheinfo in /usr/lib/modules/4.1.4-1-ARCH/kernel/drivers/base
and do not find the file cacheinfo in base to patch.

Since I have never patched a kernel before, I may be looking in the wrong place. The directions for the patch command are clear enough.  Any suggestions would be appreciated.

Re: Kernel panic -not syncing

I had this same problem with 4.1.6-1 with Arch installed as a guest in a Virtualbox VM, using encrypted partitions and LVM.

Installing the linux-lts kernel works for me, so there's some regression in 4.1.6.

Re: Kernel panic -not syncing

Version 4.2.1-1 still seems to have this issue.  This is the slowest response to a kernel bug I've ever seen...

Also, bad news for anyone who fixed this by installing the LTS version of the kernel: this bug is present in Linux-LTS version 4.1.8 currently available on the arch repos.

Re: Kernel panic -not syncing

So, we must probably wait for linux 4.3. I hope the whole system won't encounter any problem with the old 4.0.7 kernel.

Re: Kernel panic -not syncing

I see this log in the last changes on kernel 4.2.4 and 4.1.11 (lts)

commit ee2a52fc66229e0cd6213809bbba527759517ddf
Author: Borislav Petkov <bp@suse.de>
Date:   Sat Aug 8 10:46:02 2015 +0200

    cpu/cacheinfo: Fix teardown path
    
    commit 2110d70c5e58326a10e93cfefdc0b3686e2ada12 upstream.
    
    Philip Müller reported a hang when booting 32-bit 4.1 kernel on an AMD
    box. A fragment of the splat was enough to pinpoint the issue:
    
      task: f58e0000 ti: f58e8000 task.ti: f58e800
      EIP: 0060:[<c135a903>] EFLAGS: 00010206 CPU: 0
      EIP is at free_cache_attributes+0x83/0xd0
      EAX: 00000001 EBX: f589d46c ECX: 00000090 EDX: 360c2000
      ESI: 00000000 EDI: c1724a80 EBP: f58e9ec0 ESP: f58e9ea0

      CR0: 8005003b CR2: 000000ac CR3: 01731000 CR4: 000006d0
    
    cache_shared_cpu_map_setup() did check sibling CPUs cacheinfo descriptor
    while the respective teardown path cache_shared_cpu_map_remove() didn't.
    Fix that.
    
    >From tglx's version: to be on the safe side, move the cacheinfo
    descriptor check to free_cache_attributes(), thus cleaning up the
    hotplug path a little and making this even more robust.

Re: Kernel panic -not syncing

My friend had similar problem with kernel panic on linux-lts 4.1.10-2. Problem occured when he switched to lzop compression in mkinitcpio.conf. I'm using lzop on two Arch powered machines, but I had no problems myself. In the end changing back to default gzip solved problem for him.

His CPU is Intel i5-4210U

Re: Kernel panic -not syncing

I can confirm that linux-lts 4.1.11-1 fixes the issue.  I have not yet tried the non-LTS kernel.

Re: Kernel panic -not syncing

linux 4.2.4-1 is fixed... Although, I see it's already marked as out of date, and 4.2.5-1 is in testing.
I'm not sure if this thread should be marked as  SOLVED - or who's responsible for that -there've been several thread merges to date.
