After the stall, it begins to handle the events during the stall, so any sysrq will be handled once the stall is over. I have the suspicion that this has to do with SATA as the stalls happen during times of high disk activity, sometimes also after boot. Are there any tricks to get a backtrace during these stalls? Softlockup watchdog? NMI watchdog? The stalls usually take less than 10 seconds, so I'd probably have to modify the timeouts as well. Will the machine continue to work even after one of the watchdogs has triggered? Any help is appreciated.
