I haven't seen any timeout message in long time but I experience frozen network (and also the already reported panic when doing ifconfig down/up then). I have also seen strange problem which may be completely unrelated: When doing 'find . -ls' on SMB mounted drive - find was spitting the contents of the drive but never finishes. Network seemed dead but when I interrupted find with Ctrl-C I got the replies to the pings sent when it was running (e.g. thousands ms) - this looks like something was preventing RX to work and the packets were just queued somewhere. I belive I should be able to easily reproduce it. genius# vmstat -i interrupt total rate irq0: clk 43784465 1000 irq1: atkbd0 66248 1 irq5: pcm0 5877 0 irq8: rtc 5603682 128 irq9: acpi0 8820 0 irq11: fwohci0 em* 205749 4 irq12: psm0 586848 13 irq14: ata0 340844 7 irq15: ata1 61 0 Total 50602594 1155 I don't think I remember debug.mpsafenet tunable being mentioned in the threads about the problems. It prevents all the problems on my system (UP non-APIC system), including the SMB issue mentioned above. Michal
