When Vista finally died on my girl's notebook, she asked me to install FreeBSD on it, so no more viruses. I installed RELENG_8_0/i386, to compile fresh RELENG_8/amd64 in hopes SUJ will be availible (2gb RAM is kinda too small for ZFS). I've built custom kernel (GENERIC with unneeded things nodevice'd) and rebooted it, kldload if_re, ifcionfig, so ping started to work. I then attempted to mount_nfs, but it hung. "re0: watchdog timeout" appeared on console. So the thing is, re0 stops working after sending any packet longer than 536 bytes. I tested via ping, -S (536-8) works, but (537-8) leads to watchdog timeout. The host cannot be software rebooted in ~80% cases after it happened. Machine in question is Fujitsu-Siemens Amilo Pi 2540. The lines from RELENG_8 dmesg are: re0: port 0x3000-0x30ff mem 0xf0300000-0xf0300fff irq 19 at device 0.0 on pci5 re0: Reserved 0x1000 bytes for rid 0x18 type 3 at 0xf0300000 re0: MSI count : 2 re0: attempting to allocate 1 MSI vectors (2 supported) re0: using IRQ 256 for MSI re0: Using 1 MSI messages re0: Chip rev. 0x34000000 re0: MAC rev. 0x00000000 miibus0: on re0 re0: bpf attached re0: Ethernet address: 00:03:0d:a1:a8:19 re0: [MPSAFE] re0: [FILTER] Those lines in RELENG_8_0 are the same except IRQ 259 (i kldload if_re after boot). RELENG_8 is from 2010.05.04 i believe; had tried with sources as of 2 or 3 weeks earlier - same bug. No CFLAGS except -mtune=native (i doubt it does the weather). It doesn't matter if i kldload or just use GENERIC. How can i test further, except building fresh RELENG_8/i386? How to use a magic "DDB key" and what to input in there? p.s. I subscribed only to current@ so cc me if needed. -- wbr, |\ _,,,---,,_ dog bless ya! ` Zzz /,`.-'`' -. ;-;;,_ McLone at GMail dot com |,4- ) )-,_. ,\ ( `'-' net- and *BSD admin '---''(_/--' `-'\_) ...translit rawx!
