2.6.7-rc1 nenabootuje

[zde]

Tak jsem tu bugu nasel a opravil, kam mam poslat patch?
Stejne je to divny, nemohlo to behat na zadne x86 machine
bez cpuidu. Jakto ze si toho nikdo z "hackeru" nevsimnul?

Kdyz nema cpu cpuid instrukci, early_cpu_detect() nenastavi
L1 cache size, kmem_cache_init() tu nulu posle jako align
do cache_estimate(), a protoze ten je napsanej pekne blbe
tak se jim zacykli. :)

Jo, a tusi nekdo proc Linux dela takovy blbosti jako 
detekci procesoru dvakrat? 2.6.6 to delala jen jedou
a poradne. Fuuuuuj!
