I'd compare the two kernel configurations - that's far more likely to have caused problems than the version upgrade itself. Also, if possible, I'd check if it's hanging really. What you show is often caused by the output starting to go elsewhere, and the xterm's failing to appear because they were disabled in the kernel configuration; or, in this case, I'd check /etc/inittab because you maybe switched from a devfs to a non-devfs kernel, and it's still using vc/0 instead of tty0, and so on. However, do these checks to see if it's hanged: 1) is it using a lot of CPU time in top output? In that case it's a real hang maybe due to spinlocks (if you have spinlock debugging enabled, disable it). 2) can you get "uml_mconsole <umid> help" to work? Note that in > Kernel command line: ubd0s=root_fs ubd1s=swapfile ubd2s=build_fs > eth0=daemon,,,/var/run/uml-utilities/uml_switch.ctl mem=64M > devfs=nomount umlid=uml1 root=98:0 you have umlid=uml1, which is a _typo_ for umid=uml1. So fix that and try (with the uml "hanged"): uml_mconsole uml1 help it will hang for a response or answer; if it answers, on "uml_mconsole uml1" prompt you can test stuff with "sysrq". 3) test if you can ssh to it. > Any hints what I do wrong? > Thanx -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
