I just had this case today. System boots until "Loading compose keys"
message appears then nothing more happens. SysRq-T does not show
anything - just message "Show State". After SysRq-USB system came up
normally.
It means, the problem was not stale entries in /lib/dev-state or
pam_console_apply. It looks very much like symlink resolution deadlock
we had in September/October. System used to hang somewhere on startup
and usually came up normally after forced reboot using SysRq.
This is with Mandrake 2.4.17-10mdk kernel (2.4.18-pre7 based) with devfs
199.8 patch:
{pts/3}% dmesg | grep devfs
Kernel command line: BOOT_IMAGE=linux ro root=345 hdd=ide-scsi
devfs=mount
devfs: v1.10 (20020120) Richard Gooch (rgooch@xxxxxxxxxxxxx)
devfs: boot_options: 0x1
Mounted devfs on /dev
Unfortunately I have no idea how to reliably reproduce it. In my case
upon reboot system suddenly lost mouse and keyboard was dead. I did hard
reset and during this boot (immediately after hard reset) system hung as
described.
I use single ResierFS partition. I could of course try reset once more -
the question is how can I debug it if it hangs again? It hangs very
early when virtually nothing else is started.
