2.4.5: extreme sluggishness/strange OOM

A PIII with 64MB ram, 256MB swap became extremely sluggish. While still inside X11 the caps-lock LED responded only after about 10 seconds. Disk LED was continuously on. Impossible to connect from another system (just too slow) but the box still responded to ICMP echo. I played a bit with magic s

scsi disk defect or kernel driver defect ?

Hello guys! Currently my scsi disc is only reporting errors! In the adaptect scsi bios I tried the verify media option and it worked fine. The output from the Linux kernel is more than worse! Can you tell me what's wrong in my system ? I will monitor the mailing list the next hours, if the hard

ipv6: can't connect to myself?!

I can't connect() to my own link-local address. connect just hangs. Before some wise guy now tells me I should be connecting to ::1 instead: "oh, really!" ;) The application is npush/npoll from my ncp program suite, which can be found at http://www.fefe.de/ncp/. Basically, the sender sends UDP

ftape and kernel 2.4 problem

Hi! As the linux-ftape mailing list is gone I'm asking you guys. Can someone tell me how to adapt the ftape driver that I can use it under kernel 2.4.x (x >= 5)? I'm not that into kernel hacking that I know what changed from 2.2.x to 2.4.x. Below is the output of make. BTW why wasn't the newer
