Hi,

Please check v5.6-rc2 and if it doesn't help please try to do
bisection between v5.4 and v5.5 kernel versions as described in:

	Documentation/admin-guide/bug-bisect.rst

Also could you please explain what prevents you from migration to
libata drivers (CONFIG_ATA) from the IDE subsystem (CONFIG_IDE, it
has been deprecated many years ago and is scheduled for removal)?

Best regards,

Hello,
I have tested version 5.6-rc2 but I get the same result.
As for IDE drivers, they were enabled due to previous configurations.
However, following your suggestion, I recompiled the 5.5.5 kernel with
CONFIG_IDE disabled and the problem no longer occurs.
This does not explain the reason for the crash, but I solved the problem.
Thanks,
Antonio
