I have had several of those on my laptop since I upgraded to 10.0_BETA (then 10.0 then 10.1 and it still crashes the same way from time to time). My laptop is a Clevo and it also has an iwm0 Wi-Fi device. When it ran NetBSD 9, I never had any problem with iwm0. With NetBSD 10, the iwm0 firmware frequently fails to load at boot time although running dhcpcd manually afterwards generally makes the firmware to load properly. I never see throughput above 2 MB/s with iwm0 on NetBSD, which is really slow, but, when I boot the same system with Linux on an external disk, I have never had any problem with Wi-Fi and I have much higher throughput. iwm0 seems quite buggy as it is...
Thanks for answering, Marc.Yes, I have the same experience as yours. I also have frequent crashes at boot on the green kernel messages that I do not know if are related to iwm0 or i915 driver. I call it "a crash" but what really happens is that booting stops at arround second 10th. I filled a bug report here:
https://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=58585 but no news at the moment.Yes, WIFI is slow compared to Linux. I have Debian, FreeBSD and NetBSD installed on this PC. I find Wireless in NetBSD is the slowest one. Linux has by far the fastest WIFI. I have the three OSes for testing several things but the OS in which I expend 99% of time is NetBSD. I got in love with NetBSD more than a year ago and I like very much how things are done here but I must admit that it is a bit hard. I find frequent problems in the pkgsrc packages ;-)
Also have NetBSD in a Acer Aspire One and WIFI from time to time looses connections. Athn drive in that case. Also have a raspberrypi ZeroW running NetBSD using bfwm driver. It does not work very well...I have tested with a WIFI dongle with urtwn driver and it worked better but not 100%. Now I am testing the internal WIFI with bwfm driver again and have find a way that seems to run stable: I had an unused TP-LINK repeater that I have configured as an Access Point with a fixed channel in 2.4 GHz. Anyway, It seems that WIFI is not a NetBSD strength.
I am now trying to compile the kernel with debugging symbols just in case the experts can dig into this.
I am in doubt, if I compile a netbsd kernel with debugging symbols, can I use the same netbsd.1.core file or should I wait for another crash?
Thanks. Ramiro.
