Vers LK1.1.19 00:01:02:f1:83:37, IRQ 11 product code 464a rev 00.13 date 11-12-00 Internal config register is 1800000, transceivers 0xa. 8K byte-wide RAM 5:3 Rx:Tx split, autoselect/Autonegotiate interface. MII transceiver found at address 24, status 782d. Enabling bus-master transmits and whole-frame receives. 0000:00:06.0: scatter/gather enabled. h/w checksums enabled "ifconfig eth0" gives then an unconfigured eth0, ok. but using "ifconfig eth0 192.168.1.1" results in a lockup. no oops printed, no SysReq anymore. i tried with the "tulip" modul first, and could "strace" the ifconfig, until it freezes. http://nerdbynature.de/bits/sheep/network/ifc-tulip.log the 3c59x module however acted somehow differently: upon using "ifconfig eth0 192.168.1.1" the screen filled with strange chars in some pattern, i've never seen before on a linux box (no, i was clean :-)) (ok, the pattern is probably not important, but it's on [1] anyway) then, the system locked up too. as you can see (http://nerdbynature.de/bits/sheep/network/config) i have then compiled some debug options into the kernel, i loaded the 3c59x module with "debug=6". also, i want to say that this is not my first build of a 2.6 kernel, i have a i386 running pretty stable with 2.6 for weeks now; some time ago i used to have an Alpha (AXP) with 2.5.x running 24x7. please let me know, i have forgotten something or where to look further. i will be glad to help with running tests and the like. i don't suspect hw errors here, because both cards are happy working under 2.4. some details about the PrEP machine: [1] http://nerdbynature.de/bits/ Thank you, Christian. -- BOFH excuse #132: SCSI Chain overterminated
