After I've upgraded from 7.2 to 7.2.92 (Skipjack), my first several attempts at starting Mozilla (a custom-built BuildID 2002032603, not the one in the distro) resulted in kernel oops'es with machine getting stuck (usually first the KDE panel wold get stuck, then the whole X, then the rest). It took me 3 reboots to get Mozilla to start. I'll attach a file with all the relevant log messages shortly. Needless to say, I never had such problems with 7.2

Worth testing the latest rawhide kernel; it ought to be fixed there
bug fixed in 2.4.18-0.14 and later; should appear in rawhide soon
