1. Please describe the problem: thousands of lines intermittently dumped into the journal, over 3 million in a single boot Apr 21 14:24:55 fovo.local kernel: intel-lpss 0000:00:15.1: idma64_irq: status=0x0 2. What is the Version-Release number of the kernel: 6.3.0-0.rc7.20230420gitcb0856346a60.59.fc39.x86_64+debug 3. Did it work previously in Fedora? If so, what kernel version did the issue *first* appear? Old kernels are available for download at https://koji.fedoraproject.org/koji/packageinfo?packageID=8: Does not happen in any 6.2 series kernel. I'll need to narrow down the first 6.3 series kernel it appears in. 4. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below: 5. Does this problem occur with the latest Rawhide kernel? To install the Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by ``sudo dnf update --enablerepo=rawhide kernel``: Yes 6. Are you running any modules that not shipped with directly Fedora's kernel?: No 7. Please attach the kernel logs. You can get the complete kernel log for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the issue occurred on a previous boot, use the journalctl ``-b`` flag. They are too large, there's ~27 journal files, 60M each. But the full logs aren't super helpful: Unfiltered, first event appears without prior warning.

A quick search of mainline kernel git log filtered for intel-lpss, nothing shows up since October. The problem does happen with 6.3-rc7 (release), but doesn't happen with 6.3-rc1.
Bug first appears in 6.3.0-0.rc2.20230317git38e04b3e4240.27.fc39.x86_64+debug Last good version is 6.3.0-0.rc2.20230315git6015b1aca1a2.25.fc39.x86_64+debug Bug appears in 6.3.0 release.

https://gitlab.com/cki-project/kernel-ark/-/commit/9b58c93f4dba78d895238ea5c09540aa837d8736 CONFIG_DMADEVICES_VDEBUG=y is the direct result of the problem; but maybe the messages point to an actual problem. Thing is I have no idea how far back the problem could go to even entertain bisecting it.

6.11.0-63.fc41.x86_64 Still happens, makes the debug kernel impractical to use.
Upstream recommended unsetting CONFIG_DMADEVICES_VDEBUG https://lore.kernel.org/linux-i2c/20230426045127.GZ66750@black.fi.intel.com/
