>Description:

The TNF i386 testbed is now failing at the install stage, with the
INSTALL kernel reporting "panic: x86_hotpatch_apply failed":

  http://releng.netbsd.org/b5reports/i386/commits-2022.09.html#2022.09.07.00.40.19

This is installing NetBSD/i386 in a qemu VM using NVMM acceleration.

The problem appears to have started with knakahara's commit
of 2022.09.07.00.40.19 with the commit message

  NetBSD/x86: Raise the number of interrupt sources per CPU from 32 to 56.

  There has been no objection for three years.
      https://mail-index.netbsd.org/port-amd64/2019/09/22/msg003012.html
  Implemented by nonaka@n.o, updated by me.

 This also happens on real hardware:
