Linux Alpha - SX164 IRQ

Hardwareinterrupts do not work properly

• This can cause either your machine not to boot at all or strange hangs during operation
• This problem is known for all kernels up to 2.1.125
• Machine may not boot, apply this diff and try again. This diff is against 2.1.120 but also works for somewhat older and newer kernels
• Strange hangs during operation, much too long beeps, delayed response. This has something to do with the new enahnced RTC driver not working properly on SX164. If you experience strange hangs or another sympton mentioned above try to disable RTC for your kernel.
• It seems that a little patch can avoid the RTC problem. I now can use 2.1.121, the applied patch and RTC support wihtout problems so far. The patch is here (along with the mail that was posted to the axp-mailinglist).
