Yesterday, I noticed that netstat had stopped working on my 2.2.17 box
(with the reiserfs 3.5.26 patches and lm-sensors/i2c-2.5.2, as it
happens), built with gcc-1.1.2.
The reason is fairly self-evident:
: loki:/# cat /proc/net/dev
: Inter-| Receive | Transmit
: face |bytes packets errs drop fifo frame compressed multicast|bytes packets errs drop fifo colls carrier compressed
: lo:%lu %lu %lu %lu %lu %lu %lu %lu %lu %lu %lu %lu %lu %lu %lu %lu
: eth0:%lu %lu %lu %lu %lu %lu %lu %lu %lu %lu %lu %lu %lu %lu %lu %lu
Probably not right.
This is repeated in other files (I only checked /proc; its
subdirectories are probably affected too, viz /proc/net/dev above):

(really weird; half the fields OK, half %lu?!?)
/proc/ksyms contains random garbage.
/proc/ioports oopses if I try to cat it, but the oops message that
results isn't much use, as the same gremlins have been at it:

Likewise /proc/rtc.
It's not been wrong forever; it went wrong without warning at 5 days, 19
hours, 45 minutes uptime, according to procmeter.
More cats are available upon request :)
