Re: Recent amd64 auich panics

Indeed the kernel from overnight boots OK and sound works. There is some
problem with the sound in this configuration though - I use from time to
time audio/moc on this machine and noticed it has become decidedly choppy -
I don't know when, as it is the same with earlier working kernels (but
perhaps two months ago it was OK). Of course the reason for this may lay
outside NetBSD - VirtualBox sound emulation driver, Windows 10 driver etc.

There were some changes in this area yesterday which fixed a similar
problem for me, also this code probably needs fixing:

static int
auich_round_blocksize(void *v, int blk, int mode,
const audio_params_t *param)
{

return blk & ~0x3f; /* keep good alignment */
}

It should return 0x40 instead of 0 for too small block sizes.
Something like:

if (blk < 0x40)
return 0x40;/* avoid 0 block size */
return blk & ~0x3f; /* keep good alignment */

Recent amd64 auich panics

Hi,

The last few days I am getting repeated panics on amd64 -current running
under VirtualBox (latest 5.1.14 version at the moment) as follows:

If I disable auich, it boots fine.

The dmesg buffer is not saved and for some reason 'reboot 0x104' does not
produce a dump, so the above is manually taken.
