Eliminate the problems until you have stability, repeat with any device causing problems until you find stability then add things back in 1 by 1 until if crashes.
The IRQ sharing problem common in those threads can apply to other devices as well, use the ideas in the threads to solve your problem.
The 8200/8300 chipsets don't seem to like irq sharing on the PCI-E bus with current kernels/drivers.
USB 1.1 does not crash if it is enabled.
USB 1.1 does not crash if it is used by really slow devices like usb keyboard or usb mouse or if I use my adsl modem only for pinging hosts.
USB 1.1 crashes with big transfers: usb hdd, pendrives, IRDA, ADSL modem or if I ultrafast wave mouse like crazy on desktop to artificially create big data transfer from mouse.
kernel parameters workarounds the problem and except ftp and torrent downloads everything works.
I would like to find/make a fix because:
1. I do not like workarounds
2. ftp and torrent is useful sometimes.
3. WinXP SP3 has no problem so Linux has problem
That is why I try to collect info from other users to compare my system with theirs to lear what is different, what is better, what is worse.
