I've been playing with NetBSD 9.0_BETA amd64 from nyftp on a laptop for a little while and noticed a significant drop in stability sometime after Aug 18 (I have an Aug 18 kernel which seems solid, but Sep 2, 7 and 10 also panic)
The symptoms include
- netbsd-8 firefox binary segfault every time on startup. Doesn't always happen, but once it starts, they always seem to segfault until reboot. Note that though "netbsd-8 firefox binaries" are not necessarily a paragon of stability even on netbsd-8, this does not happen on -8, or even the Aug 18 kernel
- panic/reboot - almost always while interacting with that same netbsd-8 firefox binary
Interestingly savecore always seems to fail with:
savecore: dump_exists:471: kvm_read newdumpmag: _kvm_kvatop(ffffffff8180030c)
A sample panic (captured from dmesg after reboot) is below. The stack trace includes usbnet on a ure Ethernet interface on a USB port, but the panics and firefox crash loops have occurred without this attached.
Has anyone else seen similar? I'm running with the Aug-18th kernel for now without issues
Thanks
David
