That is strange - I think I saw it earlier on v240 where I am currently testing (I have seen it multiple times on v240, only once or twice on v440). Now I have also ran 4.4-rc8 on v440 for some hours and it seem to survive.

Nothing in ALOM console log history or in syslog. > It could also be influenced by either the amount of memory he has > installed, or what userland he is using. v240 has 6G RAM, v440 has 8G. Userland is Debian unstable, as it was as of July 25, 2015. gcc 4.9.3-2, binutils 2.25-10. My usage pattern on all the machines was powering up the machine, doing git pull && make -j4 && echo OK where -j number corresponds to number of CPUs in the system. Maybe git pull created some memory pressure before? ps shows I have running init udevd dhclient uuidd rsyslogd atd cron irqbalance sshd exim4 ntpd getty + sshd,bash for my login session. v440 also has /usr/bin/daemon /etc/init.d/mpt-statusd check_mpt init is sysvinit on both machines. irqbalance and ntpd are the only slightly suspicious ones for my eye, or i2c modules but these are only on v240. mroos@v440:~$ cat /proc/interrupts CPU0 CPU1 CPU2 CPU3 0: 7561 3617 5495 4128 none timer 1: 0 0 0 0 sun4u-IVEC TOMATILLO_PCIERR 2: 0 0 0 0 sun4u-IVEC TOMATILLO_UE 3: 0 0 0 0 sun4u-IVEC TOMATILLO_CE 4: 0 0 0 0 sun4u-IVEC TOMATILLO_SERR 6: 0 0 453 0 sun4u-IVEC eth0 8: 0 0 0 0 sun4u-IVEC TOMATILLO_PCIERR 13: 0 0 0 0 sun4u-IVEC TOMATILLO_PCIERR 14: 0 0 0 0 sun4u-IVEC TOMATILLO_UE 15: 0 0 0 0 sun4u-IVEC TOMATILLO_CE 16: 0 0 0 0 sun4u-IVEC TOMATILLO_SERR 19: 0 0 0 0 sun4u-IVEC power 20: 230 0 0 0 sun4u-IVEC su(serial) 21: 0 0 0 0 sun4u-IVEC ohci_hcd:usb1 22: 0 0 0 0 sun4u-IVEC ohci_hcd:usb2 23: 0 172 0 199 sun4u-IVEC pata_ali 24: 0 0 0 0 sun4u-IVEC TOMATILLO_PCIERR 31: 0 0 0 3311 sun4u-IVEC ioc0 32: 49 0 0 0 sun4u-IVEC ioc1 NMI: 0 0 0 0 Non-maskable interrupts mroos@v240:~$ cat /proc/interrupts CPU0 CPU1 0: 10073372 10074564 none timer 1: 0 0 sun4u-IVEC TOMATILLO_PCIERR 2: 0 0 sun4u-IVEC TOMATILLO_UE 3: 0 0 sun4u-IVEC TOMATILLO_CE 4: 0 0 sun4u-IVEC TOMATILLO_SERR 6: 44675 52105 sun4u-IVEC eth0 8: 0 0 sun4u-IVEC TOMATILLO_PCIERR 14: 0 0 sun4u-IVEC power 15: 0 266 sun4u-IVEC su(serial) 20: 0 0 sun4u-IVEC TOMATILLO_PCIERR 21: 0 0 sun4u-IVEC TOMATILLO_UE 22: 0 0 sun4u-IVEC TOMATILLO_CE 23: 0 0 sun4u-IVEC TOMATILLO_SERR 25: 46126 73792 sun4u-IVEC sym53c8xx 26: 30 0 sun4u-IVEC sym53c8xx 27: 0 0 sun4u-IVEC TOMATILLO_PCIERR NMI: 42625 42625 Non-maskable interrupts -- Meelis Roos (mroos@xxxxxxxx) -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
