Re: [gentoo-dev] System hangup w/ X taking 100% cpu

[Nathaniel Grady]

To add to this my really old -rc6 system I believe has similar problems - konqueror locks fairly frequently when dragging and dropping (when using as a file manager) - I never ssh'd in to check top because i don't like having any open ports on my laptop. If i ever get my brand-new gentoo install to work with PCMCIA correctly i'll report on that. I do not have this issue with Nautulus or GMC (however i do have a problem that sometmes i get stuck with the "drag and drop" mouse pointer and have to switch to another console to kill -9 gmc or nautulus - i assume that is a backbox or xmms issue). I use default optimization flags for PII in make.conf.

For anyone who is curious this is a Thinkpad 600e / 128mb ram / 366mhz PII / NeoMAGIC video / ambicom ethernet / CS4232 audio w/ oss drivers. W2K did really odd things to the IRQ/DMA assignments but i reflashed the bios and used mkfs to fix that problem :)

PS: I'm saying this in hopes that it will help diagnose the problem - I don't really expect to be able to look at much for the next week as it's finals time :( Over xmass break i do plant to get this darn thing workin right :)
