Sometimes the hang occurs a line or two later (depending on arguments?)

I meant /proc/ide/svwks, sorry.

Comment 5 John Dalbec 2002-10-30 22:24:53 UTC
The kernel-debug RPM boots fine.  It looks like this may be the SMP interrupt
routing issue that others have complained about.

kernel-bigmem boots fine with "noapic".

Comment 8 John Dalbec 2002-10-31 22:09:03 UTC
The .config fix from bug #74937 also works.
