Thanks for your suggestions. I must apologize that I was incorrect: it wasn't a problem in 2.6.7 but rather in my LILO configuration. The root for the problems was "serial console" (which was enabled for 2.6.7 but not for other kernels).
By enabling serial console, 2.6.0 had the same behaviour. By disabling it, 2.6.7 worked fine too.

Put it in If I did this with serial console enabled, the computer pretty much hanged. I had to use SysRq+S/U/S/B to reboot (which fortunately worked fine). I also got this interesting message into system logs a few times: <4>uhci_irq(hcd=f6c3fbf8), status=0x00000001 <4>uhci_irq(hcd=f6c3fbf8), status=0x00000001 <4>uhci_irq(hcd=f6c3fbf8), status=0x00000001 <4>Losing too many ticks! <4>TSC cannot be used as a timesource. <4>Possible reasons for this are: <4> You're running with Speedstep, <4> You don't have DMA enabled for your hard disk (see hdparm), <4> Incorrect TSC synchronization on an SMP system (see dmesg). <4>Falling back to a sane timesource now. <4>uhci_irq(hcd=f6c3fbf8), status=0x00000001 <4>uhci_irq(hcd=f6c3fbf8), status=0x00000001 <4>uhci_irq(hcd=f6c3fbf8), status=0x00000001 I think I don't have enough motivation/skill/time to debug this further, at least if it can be duplicated by other people. But I'm willing to help if there is some information that I should give. Let me know if there is some other place where I should report this problem. ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
