--- Comment #50 from Alexander F (superveridical@gmail.com) ---
Kernel version: 7.1.3 (Gentoo vanilla-sources, localmodconfig from 6.19.6)
linux-firmware version: 20260110
BIOS: 311 (haven't changed, no new versions)
All other software: haven't changed

First I established the failure rate baseline on the new version of the kernel.
Got "HC died" on the following number of sleep cycles with reboots in-between:
2,2,15,3,10,10. 

I used this command for testing:

while true; do sleep 5; rtcwake -m freeze -s 7; if dmesg | grep -q "HC died";
then break; fi; done; 

The patch didn't apply cleanly to this version, so I had to tweak this part
manually:

1357    /* Mandatory transition delays; see PCI PM 1.2. */
1358    if (state == PCI_D3hot)
1359            pci_dev_d3hot_sleep(dev);
1360    else if (state == PCI_D2)
1361            udelay(PCI_PM_D2_DELAY);

Unfortunately it still failed. First on the 2nd cycle, then on the 8th.

I can update firmware / other things if needed.
