2.4.0-test1-ac15, 2.2.14: hwclock hangs on /dev/rtc

I didn't bother to report it earlier but when issuing the hwclock command
it always hangs trying to read from /dev/rtc. Excerpt from strace output:

gettimeofday({961335142, 924275}, NULL) = 0
getuid() = 0
open("/dev/rtc", O_RDONLY) = 3
close(3) = 0
open("/dev/rtc", O_RDONLY) = 3
ioctl(3, 0x7003, 0) = 0
read(3, <unfinished ...>
[have to ^C]

I have a IWILL DBL100 mobo + 2xPIII 450 MHz.

Simply removing /dev/rtc is a workaround: hwclock will go directly to the
hardware. However, manipulating the hardware clock that way is unclean
for SMP.
