HPPA64: badness while freeing init memory

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Just tried 2.6.27-rc8 on a freshly installed HP 9000 L1000-44. With 
current config it boots fine but emits two badness messages while 
freeing unused initial memory (dmesg below).

I'm not subscribed to linux-parisc so please CC: any discussion to me.
