I haven’t pos­ted any art­icles on PCLinuxOn­line over the past three weeks because I b0rked my Gentoo sys­tem. I upgraded from glibc 2.2.5 to 2.3.1 and since then I haven’t been able to run cer­tain apps without wreck­ing everything else. I’ve detailed my prob­lem here and here. If any­one can help I’d much appre­ci­ate it. 

At the moment I can run most apps, but things screw up when I load any part of KDE (includ­ing Kon­quer­or) or Evol­u­tion. GTK+ (1 and 2) apps (apart from Evol­u­tion) work fine. 

Update [200303-07]: The prob­lem is with my Nvidia drivers:

Hi! I’m the guy who star­ted this thread. I finally man­aged to fix things by turn­ing off Grse­cur­ity in my ker­nel. How­ever, a very sim­il­ar (but dif­fer­ent) prob­lem emerged a few months later. It occurred around the time I upgraded glibc to 2.3.1, so I ini­tially thought glibc was to blame. After lots of exper­i­ment­ing with ker­nel con­figs, I dis­covered that I could have a stable sys­tem using Nvidia drivers if I turned high­mem off, sac­ri­fi­cing just over 100MB of RAM (I have 1GB total). 

I then came across cigar­a­fi­cion­ado’s bug report and updated nvidia-ker­nel ebuild. I com­piled a new ker­nel, this time turn­ing high­mem back on, and installed the new ebuild. The updated ebuild had no effect — using the Nvidia driver made my sys­tem unstable like before. 

My hard­ware seems fine. Memtest86 detects no errors in my RAM (2x Cor­sair XMS 512MB DDR333 SDRAM). My GeForce 3 Ti200 card works per­fectly in Win­dows and it worked per­fectly in Gentoo until Decem­ber, around the time I upgraded to glibc 2.3.1. I can­’t fig­ure out where the true prob­lem is, but I strongly sus­pect it lies with nvidia-kernel. 

That’s what you get for rely­ing on bin­ary-only ker­nel modules 🙁
