Please send me the output of pcidump -vvv so I can make sure that your device is properly detected again.

Tweacking sysctl net.inet.udp.recvspace=131072 net.inet.udp.sendspace=131072 solved the problem. Test between routers that started to drop packets over 10Mbit, now run test at 100Mbit with less than 1% drops (over 50% before). net.inet.udp.recvspace and net.inet.udp.sendspace only affect traffic generated on a machine itself, they do not affect forwarded traffic. Generating packets on the router itself isn't a good test for how well they can forward packets. Hi Stuart, I have read it many times that increasing the values do not affect forwarding performance. That is is why I was skeptical about calomel.org solution. Can you point some directions for increasing forwarding performance? I upgraded all routers to 6.7 with patches and I think problem disappears, using the same hardware. Thanks for your help, Ivo

Nevermind, after taking another close look at the Linux code I could already commit a fix. So please compile a kernel from -current or wait for a future snapshot. Your device should then work again. In case of AX201 we need to be careful about which devices are matched by the driver because there are technical differences such as which firmware image is required. In addition to matching the PCI product ID, the driver must also match the PCI subsystem product ID against a table of known values. For consistency I wrote similar matching code for AX200 devices, and it correctly matches my AX200 device. But in the AX200 case, the Linux driver uses subsystem product IDs only for marketing purposes: It makes the operating system advertise some AX200 devices with distinct trademarked names. There are no technical differences so we can just go back to matching any AX200 device as we did before. Sorry about the breakage. Going forward, I'll try to keep in mind that some things drivers written by vendors will do are not done for technical reasons...

Re: Intel AX200 Stopped Working on Latest Snapshot
Compiled a new kernel and iwx0 is back where it belongs. Thanks Stefan!

Hi All, can somwone explain me why all login sessions use /dev/drm0 and not /dev/drm1 or something like that ?

Indeed it behaves like rsync, but we read in the source something that seems to contradict it: /* * Cp has two distinct cases: * * cp [-R] source target * cp [-R] source1 ... sourceN directory * * In both cases, source can be either a file or a directory. * * In (1), the target becomes a copy of the source.

BTW, I do not remember this behaviour in SunOS, but also not in FreeBSD when I used it many years ago, although it was there. Rodrigo

Things got changed and mixed, but they are considered ordinary now, so ordinary that even a basic newbie unix book skips them entirely. I am curious even now what is the link among shell, terminal, console, tty. Even the newbies list is closed. All this will not hinder OpenBSD development, so use it as it is and try to grab some answers from internet, good or bad ones it is to you to check.
Re: Logging in/out on console while logged in in X removes hardware acceleration
Thanks for the reply. In the first place, I was wondering if creation of /dev/drm1 (same major and minor) is even possible. In Linux I can create as many devices I need pointing to the same major & minor numbers (for example creating a /dev/null for a chroot jail). If the logic is the same, then each login can create a separate device and later just remove it on logout. Yet, from security perspective it could be a bad solution ...
