Re: New panic in wdc_ata_bio_intr



Not at the moment - on the end, I committed the version with flag.

Thanks for report and testing!

Okay, can you try following patch? It puts puts back a flag for IRQ handling. If it works, I might have an idea what's happening. I think there is some rogue interrupt disturbing the state.

If it doesn't work, can you please try to compile kernel with ATADEBUG, and set atadebug_mask (possibly via ddb during boot) to 0x40?

Sorry, it still crashes the same way. I made sure all was updated before trying, I do have

ident /netbsd  | grep wdc
     $NetBSD: atapi_wdc.c,v 1.128 2017/10/10 21:37:49 jdolecek Exp $
     $NetBSD: ata_wdc.c,v 1.108 2017/10/15 11:27:14 jdolecek Exp $

     $NetBSD: wdc.c,v 1.285 2017/10/15 18:02:33 jdolecek Exp $

and the panic is exactly the same. 

I am sure I will sort out my problem on this particular machine if I swap the internal SSD and the one in the DVD bay, placing the NetBSD root in the proper place, but nevertheless the panic may indicate some other unfinished work, so I shall keep it as it is for testing.

Hi,

should be fixed in rev. 1.285 of dev/ic/wdc.c, can you please check?

It still panics the same way, no difference. 

On my other laptop, an HP EliteBook, I haven't the problem at all, only on the two T61p's (one of them stopped working a week ago, though).

Can you try attached patch?

The timeouts when running under VirtualBox disappeared, but of course the panic on my T61p remains.

Hey,

can you try with dev/scsipi/atapi_wdc.c 1.128? That should resolve the timeouts for atapi, at least it did for me.

I get that also on VBox, except it doesn't try to add cd0a as a swap
device, nor does it show an endless stream of "lost interrupt"
messages; eventually I get a login prompt. This is with yesterday's
latest -CURRENT.
