Description of problem:
4G/4G memory split was enabled in all i686 FC2 development kernels
after version .118. This has caused several problems with various
kernel components that need to be individually isolated, confirmed and
fixed. This is the master tracking bug for both suspected and
confirmed 4G/4G problems.
Please nominate bug numbers as comments within this report, and add it
to the Bug dependency list after they are confirmed 4G/4G problems.
For your convenience I will try to maintain the latest FC2 devel i686
kernels rebuilt here with 4G/4G disabled in order to aid end-user
testing. Please test both the official kernel and this rebuilt test
kernel and report any differences in behavior.
there is no such thing as "the" 4g/4g bug nor is 4g/4g broken so this
tracking bug makes no sense really.
I have a problem that was previously diagnosed as this one, if it is
not this problem, please let me know what extra info you need to
classify the bug.
I have cold booted my notebook with no PCMCIA devices (ie. without the
card which invokes the previously noted buggy hermes driver). I have
booted without rhgb and with initdefault 3 so as to never run X.
The first suspend is successful and reports some messages, namely:
divert: not allocating divert_blk for non-ethernet device sit0
spin_lock(arch/i386/kernel/time.c:0232be08) already locked by
spin_unlock(arch/i386/kernel/time.c:0232be08) not locked
blk: queue 19d93c00, I/O limit 4095Mb (mask 0xffffffff)
I can resume OK 50% of the time it seems.
On the second suspend / resume the machine starts the fan and hangs.
Starting the fan is what happens on a cold boot.
