System: NetBSD 9.99.96 (GENERIC) #0: Tue Apr 12 11:54:57 UTC 2022 - daily snapshot
Architecture: x86_64
Machine: amd64
>Description:
Attempting to run a daily snapshot of a XEN3_DOM0 kernel with Xen 4.13 and 4.15
fails with timeouts on wd (ATA) and mpii (SATA/ATA) devices.
Xen version does not matter.
GENERIC boots flawlessly
Xen/XEN3_DOM0 experiences many timeout errors
Looks like issues with interrupts

sad news: SCSI/SAS controllers (ahd and mpii) still run into timeout and
get stuck there. as ahd gets fully stuck the boot does not finish.
disabling ahd and mpii allows to enter single user, but ahci devices
somewhat work but experience device timeouts.

Better:
- boots
- xl list works
- mpii works with tape/disk devices
But
- ahd experiences two timeout during boot
- ahd recovers later on and the tape on that device can be accessed
ahd attaches like this:

do you see these timeouts with GENERIC, or not ?
do these timeouts happen on every boot ?

no timeouts with GENERIC.
timeouts occur on every Xen boot so far.
