I no longer see those errors if i revert those 2 patches. Testing if everything is/was working i did find out that ping times to other server connected by gig-E (cupper) is not what i suspect of it: newsgate:~# ping spool1.int.newsserver.nl PING spool1.int.newsserver.nl (192.168.30.29) 56(84) bytes of data. 64 bytes from spool1.int.newsserver.nl (192.168.30.29): icmp_seq=1 ttl=64 time=4294967296000 ms 64 bytes from spool1.int.newsserver.nl (192.168.30.29): icmp_seq=2 ttl=64 time=4294967296000 ms 64 bytes from spool1.int.newsserver.nl (192.168.30.29): icmp_seq=3 ttl=64 time=4294967296000 ms 64 bytes from spool1.int.newsserver.nl (192.168.30.29): icmp_seq=4 ttl=64 time=4294967296000 ms --- spool1.int.newsserver.nl ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 2997ms rtt min/avg/max/mdev = 4294967296000.146/4294967296000.217/4294967296000.362/46340.950 ms I honestly don't know which kernel didn't do this as i've never tested/seen it before. This machine IS SMP , Processor #0 15:5 APIC version 16 ACPI: LAPIC (acpi_id[0x02] lapic_id[0x01] enabled) Processor #1 15:5 APIC version 16 WARNING: NR_CPUS limit of 1 reached. Processor ignored. But when i use 2 processor's the performance drops _under_ UP usage !? It think the cpu's are fighting for the IO IRQ's (2 x scsi controller & 2 x gig-E ethernet controllers) Any ideas/suggestions about this ? OK, thanks, I guess I'll drop those mm patches. wrt the negative ping times: don't know. Does 2.6.13 do that as well? Andrew, can we close this bug? |
