Hi there,
my soundcard works only in 50% of the boots.

Driver Info #0:

Attached to: #10 (PCI bridge)
If the card is recognised well the card works out of the box, but in
half of all boots the card is not recognised. For some reasons the card
didn't get an interrupt and then the card is not available in
/proc/asound/cards
working state:

In the not working state the cards get no interrupt, but the interrupt
above ( 18) in not given to another card or something

Board is an Asus PRIME Z270-K with bios 1207.
I have tested the card in another pci port and also have changed the
card to a new one, both without success.
Can you please help me to debug this further? When you need additional
information, please ask and I will provide it.
I have tested the card with a friend of mine in another pc without
problems, so it is save that the card works.
After asking in forums and alsa user mailing list, I don't know how
further. So I have try to debug this on my own.
Since this is the first time in my life, that I try to debug the
kernel. So I really would appreciate advice.
❯ cat /lib/modules/5.9.0-2-amd64/build/.config|grep CONFIG_DYNAMIC
CONFIG_DYNAMIC_MEMORY_LAYOUT=y
CONFIG_DYNAMIC_DEBUG=y
CONFIG_DYNAMIC_DEBUG_CORE=y
CONFIG_DYNAMIC_FTRACE=y
CONFIG_DYNAMIC_FTRACE_WITH_REGS=y
CONFIG_DYNAMIC_FTRACE_WITH_DIRECT_CALLS=y
CONFIG_DYNAMIC_EVENTS=y
It seems that my kernel support debugging.
So I set:
echo "module snd_* +p" > /sys/kernel/debug/dynamic_debug/control
echo 8 > /proc/sys/kernel/printk
boot options
/proc/cmdline
BOOT_IMAGE=/rootfs/boot/vmlinuz-5.9.0-3-amd64 root=UUID=540aa15f-af6b-
45ff-b6ad-37181400efc9 ro rootflags=subvol=rootfs
rootflags=subvol=rootfs quiet net.ifnames=0 biosdevname=0
log_buf_len=1M printk.devkmsg=on debug
After the boot the soundcard is not working, so I removed the
rmmod -vf snd_emu10k1 modul and tried reloading it.
Sorry, the output is very large and long. Is my way correct?
Or should I do something diffferent? I think better would be to
generate the debug output directly at boot, since I can't say if
removing the module causes this messages.
Please add some light to me and help me to get know whats wrong and
also please add me to CC, since I'm not subscribed to the list.
Thanks Micha

IIRC, this is a very long-standing problem, and it depends on the
motherboard.
I'd start trying to increase the delay in the probe. Although I
thought that this didn't help in the past, maybe still worth to try.
Independently from the emu10k1 probe failure, the following Oops has
to be fixed:

I suppose this is something to do with emu10k1, but do you know what
file read triggers this? If it always happens after the probe
failure, it should be easy to identify.
thanks,

How can I increase the delay for the probe?

To create this error, I only need to:
rmmod -fv snd_emu10k1
and
insmod snd_emu10k1
insmod: ERROR: could not load module snd_emu10k1: No such file or
directory
But at the moment i can't reproducing the oops. In debian there has
been a kernel update to 5.9.9-1, maybe it was fixed.
