So I kidnapped his bugzilla report :-) In the bugzilla entry I said earlier today that "hpet=disable" apparently makes the problem go away (42 boots OK so far, whereas without this boot option it hangs ~90% using vga=6 and ~10% using vga=0x0364) I tried to bisect it, but sometimes in pre 2.6.25-rc1 kernels it takes 30 boots before the first hang to occur. So bisection is not reliable... If someone proposes a patch I will be glad to test it! PS: The similar bug in buzilla 10377 also appears to be "fixed" by using hpet=disable, see comment #17 in that bug.
