Patch merged into master: f2674cc i82801gx: read RTC status register to prevent IRQ storm
by gerrit＠coreboot.org June 29, 2011

June 29, 2011

the following patch was just integrated into master: commit f2674cc3d7e90ed01af8449f8786aa7f42cb84b8 Author: Sven Schnelle <svens(a)stackframe.org> Date: Wed Jun 29 15:05:28 2011 +0200 i82801gx: read RTC status register to prevent IRQ storm My Thinkpad appeared dead. After investigation, it turned out that the RTC Alarm was triggering an RTC PM1 SMI, but the SMI handler didn't read the status register, so it was triggered again. This is a really nasty situation, as it means you have to dissemble your Notebook just to unplug the RTC battery.
