I have a fighting chance of mostly finishing a bisect over the weekend, I'll let you know where that leads. pgpVQUlUm7ZLN.pgp Description: PGP signature
next-20150610 - repeated hangs at e1000e_phc_gettime+0x2e/0x60
I'm seeing repeated hard lockups on my Dell Latitude E6530. Helpful info: 0) next-20150603 works, so the problem landed in linux-next in the last week. 1) All 3 times happened while I was at home, using wireless, so the interface didn't have link and was ifconfig'ed down. 2) Remarkably similar times for it to blow up: [14513.365378] Kernel panic - not syncing: Watchdog detected hard LOCKUP on cpu 1 [14482.271716] Kernel panic - not syncing: Watchdog detected hard LOCKUP on cpu 3 [14479.906820] Kernel panic - not syncing: Watchdog detected hard LOCKUP on cpu 0 (I suspect the offsets were caused by differences in how long it took me to correctly enter the cryptLUKS passphrase for my encrypted root filesystem) Oddly enough, I don't see any patches to the e1000e driver in quite some time... but that's where it keeps locking up. This ringing any bells?
