G'day,
I've just updated a system to 2.2-current as sup'd on Jan 6 and I'm losing
lots of packets on a local BASE2 network. The system is configured like
this:
FreeBSD 2.2-CURRENT #0: Tue Jan 9 13:39:55 EST 1996
jb@freebsd1.cimlogic.com.au:/u/freebsd/src/sys/compile/FREEBSD1
CPU: i486DX (486-class CPU)
real memory = 8388608 (8192K bytes)
avail memory = 6877184 (6716K bytes)
Probing for devices on the ISA bus:
sio0 at 0x3f8-0x3ff irq 4 on isa
sio0: type 16550A
sio1 at 0x2f8-0x2ff irq 3 on isa
sio1: type 16550A
fdc0 at 0x3f0-0x3f7 irq 6 drq 2 on isa
fdc0: NEC 765
fd0: 1.44MB 3.5in
wdc0 at 0x1f0-0x1f7 irq 14 on isa
wdc0: unit 0 (wd0): <Conner Peripherals 850MB - CFS850A>
wd0: 812MB (1664208 sectors), 1651 cyls, 16 heads, 63 S/T, 512 B/S
ie0 at 0x360-0x36f irq 7 maddr 0xd0000 msize 65536 on isa
<3C507 R1> ethernet address 00:60:8c:5b:06:4a
npx0 on motherboard
npx0: INT 16 interface
new masks: bio c0004040, tty c0030098, net c0030098
The ethernet card is a 3COM Etherlink 16.
I sometimes run NetBSD 1.1A on the same hardware using another disk and
the network works fine (I just tried this again to prove to myself that
it _still_ works fine). With FreeBSD, though, I have problems with things
like NFS (client writes from FreeBSD lock access to the NFS mounted
directory), ftp is very slow, rlogins don't always succeed... ping to
other machines on the network reports up to 39% packet loss. ping from
other machines to the FreeBSD machine reports 0% loss. The FreeBSD
figures are worst when the machine is loaded (like a compile).
I was having problems before the last sup, so I upgraded to see if life
was any better. Its not. 8-(. Is it me?
Any help would be appreciated.
Regards,
