Kernel 2.2.14 pure
patched with 2.2.15pre19
by hand changed _ONLY_ /usr/src/linux/drivers/char/serial.c:
*start = page + (begin-off) with *start = page + (off-begin)
compiled new kernel, reboot:
at start, via crontab:
2 setiathome running
sysstat running
then started:
while :; dd if=/proc/tty/driver/serial of=/dev/null bs=1024 2> /dev/null; done
Now >2h uptime writing this mail, with original serial.c uptime <=10 seconds

Many thanks to
Sebastien (innocent) which with sysstat caused the firsts crashes on my SMP,
Andrea with his immense patience helped my to find the offending code
and give me a patch to check if true,
Manfred to localize the exact point of the bug.
Regards
Mario
