from 6.9.7 to .9 ... ioremap on RAM at 0x0000000030000000 - 0x00000000301e7fff

Hello ALL , Seems I may have a memory issue here Or is this something else ? If others are seeing this then it might be something else .

The system with present memory passed a 3+ passes of memtest86+ before having slackware current installed .

This has happened more often under 6.9.9(9 times) than 6.9.7(once) & 6.9.8(three) . And not happening at every reboot .

If this is memory please just say so . I'll dig at it and find the culprit dimm .
If Not please give me pointers where to do more digging &.or research .

slackware current and (finally) upto date today .
