Several Different kernel related (?) problems



We have a rack of almost identical Supermicro P4SCE machines.
(differing disks, ram and cpu)

On these we have recently seen the following problems.

1. Screen goes blank during boot menu.
   Then there is massive on-screen image corruption until
   the fb is reset by init somewhere. In the beginning you
   can make out the text, but there are outlined squares all
   over the monitor. When more text appears it seems to make
   a mess all over the screen.
   What kernel: All FC2 kernels, ever since atleast test1

2. One of the computers will not boot on a kernel newer than
   kernel-smp-2.6.5-1.358. The following kernels fail with
   what seems like ide problems (VERY hard to make out due to bug #1)
   kernel-smp-2.6.6-1.435, kernel-smp-2.6.6-1.435.2.3,
   kernel-smp-2.6.7-1.494.2.2, kernel-smp-2.6.6-1.427
   It seems like one of the disks (2 sata in raid 1) is reported
   as failed, an it is rescheduling something. Then it stops.

3. All of our FC2 servers recently (3-4 days ago) stopped serving
   http pages to mac computers. I have no idea why, but customers
   from all over is complaining that their mac machines cannot
   open the webpages. Windows machines on the same net works.
   The mac machines has tested IE and newest Safari.
   It seems like a FC2 yum update triggered this event, but we have
   no idea how and have no way of doing testing as we don't have any
   macs.

4. One of our servers is having BIG problems with uneven intervals
   recently. The last week it has had problems about 5-6 times I think.
   Very (VERY) suddenly the load increases to 700+ and https gets OOM
   killed rapidly. Network connectivity is immedeately offline and
   console responce is _BAD_. I once waited 5min for a password prompt
   before I had to reboot it due to customer complaints.
   I saw the 700-900 load climb once when I had let top stay on console.
   This has occured only since after Monday.


Hardware info below is from the server that won't boot new kernels, for
more info please ask and I will provide.

Sincerly
    Hans Kristian Rosbach
