(usagi-users 00640) problems on SNAPSHOT 20010709

[NISHI Takao <zophos@xxxxxxxxx>]

Hi.

I have two problems on USAGI SNAPSHOT 20010709's linux22 kernel (i386).
Does anybody have counter-plan or information?


1. Many "bug: kernel timer added twice at c0186f51." message are
recorded on kernel log at every 5min. 
That is not occured on SNAPSHOT 20010611.

In my opinion, the code, kernel/linux22/net/ipv6/addconf.c:1683 

void addrconf_verify(unsigned long foo)
{

                  :
     addr_chk_timer.expires = jiffies + 1*HZ;
     add_timer(&addr_chk_timer);
                  :
}    

causes this problem. (But I have no counter-plan.)


2. Every a day or two days, the kernel makes panic and freeze. That is
not occured on SNAPSHOT 20010611 too.

Tipical Oops log as;
