Yesterday I reported a problem installing FC4t3 on the subject machine. I've reproduced this problem multiple times on this machine, both on FC4t3 *and* on FC3. I now have a keyboard with working F3 and F4 keys :) so can report what is on those virtual terminals at crash time. Here is a report for the crash toward the end of installing FC4t3. Virtual terminal 4 is the only one that shows something interesting. I only see 29 lines of text; the rest have scrolled off the top of the screen. The visible lines show multiple instances of this line pair: <4>Error -3 while decompressing! <4>AAAAAAA(BBBB)->CCCCCCC(4096) where the AAAA and CCCC are hex and the BBBB is decimal less than 4096. These three numeric strings vary among the many instances of those paired lines. Toward the top of the screen (remember, only 29 lines are visible), I see this line: <6>anaconca[570]: segfault at ffffffffc482f918 rip 00002aaaadcca001 rsp 00007ffffff9b3c8 error 6 This <6> line appears after one visible <4> line pair, and twelve of the <4> line pairs follow it. At the bottom of the screen is this line: <6>anaconda[557]: trap invalid operand rip:2aaaae204000 rsp:7ffffff9ce08 error:0 Is this helpful for tracking down the problem? I'll next trigger the FC3 installation fault and report what I see. David
