Hi.
When running 'tar cvIf <file> /' or 'tar cvzf <file> /' (but sometimes not
with 'plain' tar, i.e., without compression) I get an oops after some
time. This is reproducible. The oops below is from a 'tar cvIf' run.
I get this also with 2.2.17pre10 (which was what I was running before
encountering this) but not with the stock RH 6.2 kernel (2.2.14-5.0).
Unless I get other suggestions I'm going to try with the latest 2.2.18pre
and 2.2.16 tomorrow.
Since I had just experienced RAM problems on another machine I put in
some new RAM after testing it with memtest86, but that did not solve
the problem (neither did the old RAM show any errors when I memtested
it afterwards).
I'm not sure about the warning. Is it fatal? And what should I do to get
rid of it?
Comments appreciated and info willingly given :)
