I have not been able to get my laptop to run 2.6.21-rc2-mm1 for more than 5 minutes. The last kernel I had working was 2.6.20-rc6-mm3. The problems may be multiple. Whenever I load the new bcm43xx drivers and do *anything* with iwconfig, it locks hard. No keyboard LEDs, and sysrq does not work. While I had it in single-user mode, no bcm43xx drivers loaded, I was using make menuconfig to try a different configuration, and it locked hard for no apparent reason. Again, no keyboard LEDs, no sysrq. Laptop fans come on full speed after a bit, so something is still happening in the BIOS. -- Zan Lynx
