hello,
we've been seeing a number of eepro100 cards "stuck" in a mode with
very poor response over the last couple of weeks. with that, i mean
(a) ping times is unacceptably high (1/10 of a sec)
(b) throughput is less than 100kbit/s (measured by ttcp)
a reboot fixes the problem.
machine details:
- Intel STL2 motherboard (latest bios revision)
- eth0: OEM Intel i82559 rev 8 (onboard)
- linux kernel 2.4.19 (custom)
- eepro100.c:v1.24 7/25/2002
most of these machines had been up (and used continuously) for 250+
days when the trouble started to occur a couple of weeks ago.
the kernel debug logs only contains
kernel: eth0: Unknown receiver error, status=0x5048
kernel: eth0: Unknown receiver error, status=0x5148
the output of "eepro100-diag -faem" is attached and shows pending
interrupt sources.
what is this and does anyone know how to cause/fix it?
will a simple driver/kernel upgrade do, or should i look for
something else that may be wrong?
regards,
