I used RH 5.1, 5.2 and 6.0 on my Cyrix 6x86 166+ processor, but when I installed RH 6.1 sig11 appeared, I thought my hardware is broken, but on newsgroups I meet another person with the same problem. Now I use SuSE 6.2, and see no sig11 no more... It _is_ bug in RedHat 6.1, but not in kernel (I compiled myself many, even tried old kernel from my old system), I am not sure what is it - glibc? gcc? Please answer.. I want to back to RH...
Its not uncommon to see cyrix in paticular with overheat or cache errors that bit depending where some things land in kernel space
