Hi,
even though I've been using Slackware for quite some time (I installed it for the first time at the beginning of 1994 and used it ever since), this is my first post here and I must admit I was reluctant since I know mine is not a slackware specific problem (probably with slackware there are not distribution specific problems, but just general linux problem..
, but something hardware related, even though there is something I cannot grasp and, maybe, some fellow slackware user may point me to the correct direction...
I recently bought 3 used HP ProBook 654 G1 laptops. Even though the hardware is almost identical, they come in 3 different flavors:
- machine A: AMD A6-4400M, bios version 1.47, Trinity 2 [Radeon HD 7520G]
- machine B: AMD A6-4400M, bios version 1.31, Trinity 2 [Radeon HD 7520G]
- machine C: AMD A6-5350M, bios version 1.31, Richland [Radeon HD 8450G]
I started with machine A and I installed slackware64 current (updated 25/12/2019, kernel 5.4.7), with alienBOB's ktown. Everything worked smoothly and the system was properly configured without any problem.
So I copied the root partition of machine A to machine B and C. Everything seemed to be fine till the first suspend-to-ram/resume cycle:
- at the first resume both machine B and C report an "no irq handler for vector" error:
Code:
[ 247.968483] smpboot: CPU 1 is now offline
[ 247.969211] ACPI: Low-level resume complete

-> [ 247.972121] do_IRQ: 1.55 No irq handler for vector
[ 247.972568] CPU1 is up
- at the second resume both machine B and C report two "no irq handler for vector" errors:
Code:
[ 306.514332] smpboot: CPU 1 is now offline
[ 306.514985] ACPI: Low-level resume complete
[ 306.515068] ACPI: EC: EC started

[ 306.515630] x86: Booting SMP configuration:
[ 306.515631] smpboot: Booting Node 0 Processor 1 APIC 0x11
[ 306.515834] microcode: CPU1: patch_level=0x0600111f
-> [ 306.517897] do_IRQ: 1.55 No irq handler for vector
[ 306.518371] CPU1 is up
After a deeper inspection I found that all the 3 machines, at boot time, show that same kernel error:
Code:
[ 0.365713] x86: Booting SMP configuration:
[ 0.365779] .... node #0, CPUs: #1
[ 0.011654] do_IRQ: 1.55 No irq handler for vector
[ 0.366755] smp: Brought up 1 node, 2 CPUs
But only machine B and C report the errors when resuming.
I then started searching for the problem and the possible solution, and I found these interesting threads:
https://lkml.org/lkml/2018/2/24/63
https://lkml.org/lkml/2019/2/19/797
The error seems to be related to the BIOS and, as you noticed, machine A is running a more recent version. So I upgraded the BIOS of machine B and C and, you may guess, nothing changed.
I started looking deeper at the differences of these machines: boot logs are the very same till udev is started, then only the ordering of hardware activation changes.
The only difference I can spot between machine A on one side and B and C on the other is in /proc/interrupts:
Machine B and C report:

This is present only in machine A:
Code:
29: 0 741832 PCI-MSI 524288-edge
I don't really know if this is relevant - searching I found that this is usually sent to the amdgpu driver, which is not loaded in my machines.
I've run out of ideas but I keep finding it weird that, if the issue is the BIOS, machine A is not showing the same problem.
The problem is just annoying, to quote Thomas Gleixner, but after linux-4.15 the issue is reported with a pr_emerg_ratelimited, and syslog will broadcast it to every terminal. I'm using many terminals and this problem forced me to change syslog.conf, a solution I don't like. I could try patching the kernel as described here:
https://lkml.org/lkml/2019/3/6/188
but compiling and installing a custom kernel in a slackware-current setup for a laptop is just too much work.
Any idea or direction would be greatly appreciated.
Thanks,
andrea
