Red Hat Bugzilla – Bug 134167
serial installs broken without the "nofb" option
Last modified: 2007-11-30 17:07:04 EST
Description of problem:
When kickstarting machine with "console=/dev/ttyS0,9660n1 and "text",
we get no output to the serial link unless we also specify the nofb option
Perhaps console=anything should automatically involk the nofb option?
If not, at least document this "feature", in the Installation Guide
Version-Release number of selected component (if applicable):
Section 4.3.3. Additional Boot Options of the Installation Guide
even gives an example of a serial install:
linux text console=<device>
This doesn't work (you don't see anything down the serial link)
without the nofb option being added
You want console=ttyS0,9660n1, not /dev/ttyS0.
Yes yes... that is what I meant. *That* doesn't work without nofb
I'll also note the ",9660n1," isn't documented anywhere in the
Please respond.... "serial" != "serial" unless you *also* add "nofb".
This isn't documented anywhere. Either the documentation needs to
change, or (a better fix IMO) the keyword "serial" needs to
automatically include the logic that is involked by nofb.
Fair enough... U4 should have it so that serial implies nofb.
Cool! How about a fix for this in FC3+ and RHEL4 ?
I already played branch monkey yesterday and merged the change across
all of taroon-branch, rhel4-branch and HEAD.
Excellent! If the changes have really made it into RHEL4 and
Fedora/head, perhaps we can close this.
