incorrect panic("failed to get clock for system timer"); ??

Hi,
Newbie debugging Linux-2.6.32-9 on S3C2450, the kernel seems to panic at :
s3c2410_timer_init () at arch/arm/plat-s3c/time.c:256

if (IS_ERR(timerclk))

        panic("failed to get clock for system timer");

more precisely 'if (IS_ERR(timerclk))' is non-null !?! although the 'timerclk' seem to be fine:
(gdb) print *timerclk
$27 = {list = {next = 0xc04a933c, prev = 0xc04a93ac}, owner = 0x0, parent = 0xc04abfd4, name = 0xc042c5a1 "timers", id = -1,
usage = 0, rate = 0, ctrlbit = 1024, enable = 0xc009631c
<s3c2443_clkcon_enable_p>, set_rate = 0, get_rate = 0,
round_rate = 0, set_parent = 0}
(gdb) s
257 panic("failed to get clock for system timer");
(gdb) print (unsigned long)(timerclk)
$28 = 3226112884
(gdb)

I'm not sure why 'IS_ERR(timerclk)' is holding true? or is it a bug ? thanks,
ferar

Looks to me like a compiler bug. Your timerclk is 0xC04A9374, which certainly isn't a value which IS_ERR() should return true for.
