gem(4)-related panic?

My PowerMac G4 (AGP Graphics) recently panicked with (transcribed by
hand from console):

trap: pid 239.1 (make): user read DSI trap  <at>  0x2b3 by 0x181c460 *DSISR 0x40000000, err=14)
gem0: can't load rx DMA map 79, error = 22

saved LR(0x5a5a5a56) is invalid.

Issuing "reboot" at DDB prompt seemed to hang.  Upon pressing the reset
switch, the machine sounded its startup chord, but the display remained
blank.  Power-cycle has same effect.  There is no indication that it
has probed for the USB keyboard even after significant time since reset
or power-up.

Potential hardware issues aside, has anyone seen anything like this
since the recent changes to gem(4)?

port-macppc officially dead


I hate to say it, but it seems that macppc is officially not usable for 
production any longer. NetBSD 5 was the last macppc release that was 
consistent and stable for any length of time. Anything newer will lock up 
in tstile after a few weeks to a month at most.

It's sad when hardware has to retire before its time!

DKWEDGE_METHOD_APPLE not working as expected


With DKWEDGE_METHOD_APPLE in the default kernel, partitions created using 
the old A/UX partition types (Apple_UNIX_SVR2) now are thought to be sysv 
partitions and are not automounted. I can't really imagine a scenario 
where this is a desirable result. Can anyone explain? Or should I fix it 
to properly identify such partitions as ffs?

package problem - atf-0.20 - pkgin says it is available, but it's not.

I'd like to update my MacPPC system, but there is a bug somewhere in the binary packages.

I really like the new pkgin command. It makes like SO much easier.

When I go to upgrade, I get this:

+mercy$ pkgin upgrade
calculating dependencies... done.

3 packages to be upgraded:

sysupgrade-1.4 atf-0.18

3 packages to be installed (0B to download, 1745K to install):

sysupgrade-1.5nb1 atf-0.20

proceed ? [Y/n] n

If I go ahead and say "yes", the install of atf-0.20 fails.

Something in the packages is not built, or the database is wrong.

Where is the appropriate place to report this problem?

Wifi USB dongle usable on macppc?


what options are there for using a USB wifi dongle with a USB 1.1 Power 
Mac (G3 Pismo, G4 Titanium, or B/W G3/300) running NetBSD?

Yes, I understand the speed limitation, but I'd like to use WPA2 over

TSTILE lockups - not dead yet

Got ddb working after my last lockups:

When moving from NetBSD 5 to NetBSD 7, the only change I made was I 
enabled WAPBL for the root filesystem. For whatever reason, I didn't 
enable it in the past.

Lockup issue with NetBSD 7


I just upgraded a PowerMac 9600 from NetBSD 5 to NetBSD 7 (netbsd-7 from 
11-November-2015) and so far I've had two lockups. The first time I didn't 
have anything plugged in to the serial port. Plugging in a cable to try to 
see what was wrong before rebooting gave a spontaneous reboot. I left the 
serial cable installed, just in case, and when the second lockup happened 
it was unresponsive. Sending a break to get to ddb caused an immediate 
reboot. No crash dump ever occurred.

Here's the reboot when sending a break after lockup:

~Stopped in pid 0.2 (system) at  netbsd:zstty_stint+0x1b8:       b       netbsd:z

0x10003fe8: at 0xfffffc
saved LR(0x4141413d) is invalid.rebooting

Is anyone else having lockup or ddb issues with NetBSD 7?
