The 'String of oopses' was a red herring. It was fixed sometime in early January. The PANIC: INIT: problem, however, is real, and was introduced by the following ChangeSet on January 7: D 1.972 03/01/07 10:08:55-08:00 torvalds@home.transmeta.com 15824 15815 2/0/1 P ChangeSet C Move x86 signal handler return stub to the vsyscall page, C and stop honoring the SA_RESTORER information. C C This will prepare us for alternate signal handler returns. If I build a kernel WITH this changeset it fails; if I build a kernel at 1.971 (bjorn_helgaas's i810/i830 AGP patches) the kernel works just fine. So, something in your changes to kernel/sysenter.c or kernel/signal.c causes INIT to PANIC and fail. So, what would you like me to test, now? -derek -- Derek Atkins, SB '93 MIT EE, SM '95 MIT Media Laboratory Member, MIT Student Information Processing Board (SIPB) URL: http://web.mit.edu/warlord/ PP-ASEL-IA N1NWH warlord@MIT.EDU PGP key available
