[Bug 1034357] Kernel 4.10.9: Computer Intermittently Reboots
http://bugzilla.suse.com/show_bug.cgi?id=1034357 http://bugzilla.suse.com/show_bug.cgi?id=1034357#c14 --- Comment #14 from Borislav Petkov <bpetkov@suse.com> --- Ok, here's the explanation. The MCE you're seeing is trying to tell us this: "NB WDT timeout due to lack of progress. The NB WDT monitors transaction completions. A transaction that exceeds the programmed time limit reports errors via the MCA. The cause of error may be another node or device which failed to respond." And the address reported is the physical address for which that transaction failed to complete and hit the watchdog timeout: ADDR fea00040
From /proc/iomem, the rtl8192ce wifi card occupies this range:
fea00000-feafffff : PCI Bus 0000:02 fea00000-fea03fff : 0000:02:00.0 fea00000-fea03fff : rtl_pci so it looks like your wifi card didn't complete a transaction to or from memory in the programmed time limit. Or the time limit was too short and I can imagine due to loaded network traffic, packets getting delayed and ... purely hypothetically, of course. However, the driver or the card or the firmware: [ 20.005960] rtl8192ce:rtl92ce_read_eeprom_info [rtl8192ce]:<0-0> Chip Version ID: B_CHIP_92C [ 20.015986] rtl8192ce: Using firmware rtlwifi/rtl8192cfw.bin should *actually* handle such timeouts much more gracefully or increase the timeout or whatever. So if you can't reproduce reliably and this almost never happens, I'd say, forget it and enjoy your life. :) If you can actually reproduce it pretty reliably, then I guess we should talk to the network driver author to see what he has to say. Maybe Larry has seen it already and knows what the problem is. HTH. -- You are receiving this mail because: You are on the CC list for the bug.
