I've never had the issue with TS boards but I have with older e100
drivers (Intel Pro/100) failing out after a while. I ended up setting
up a cron job that rmmod/insmod'd the module every couple hours, not
exactly ideal but it worked.
Before thinking hardware failure tho I'd try a different kernel, it's
probably the driver crapping out. Check dmesg, see if the module tossed
any errors. Also, are you running anything CPU intensive that might
cause a ISR to not be serviced and cause a buffer overflow in the MAC?
