Description of problem:
Per bug 176624, I was attempting to upgrade my FC3 x86_64 install to FC4. However, after booting off
the CD (either "linux" or "linux text"), selecting "skip" for CD testing, anaconda would run with:
<kernel panic -- I'll attach shortly>
the kernel panic would happen no matter what options I tried, always refering to the serial port. After
swearing a lot, I was about to give up looked through BIOS and found that there's a com2 which I had
disabled because there is no physical com2 serial port on the machine. For kicks, I enabled it, and then
anaconda had no problems and things progressed. Looking at the serial console output, it looks like
when the serial port is disabled, the kernel is still able to see it with an IRQ of -1, and I'm assuming that
the kernel dies when trying to access it since it doesn't actually exist.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. insert FC4 disc
2. boot off the CD

serial console output showing kernel boot and panic
Please let me know if you need any more information. Thanks.
moving to kernel component -- I put anaconda on originally since that's where the panic was happening,
but since it's a panic it's the kernel ... sorry. ;)
ok, it sounds like you managed to get it installed at least. After installing
the latest update kernel, does it crash at any stage in the same way ?
I haven't seen a crash since changing the BIOS option. I didn't change it back after the upgrade was
completed, so I can't say whether or not it was related to the kernel used in the installer or if it's still in the
ok, then I'll close this out.
