Ticket #10702 (new defect)
AHCI timeouts on heavy I/O
|Reported by:||Kohtala||Owned by:|
I tried compiling Ångström distribution on my i7 with four virtual CPU. AHCI starts to timeout during build and causes filesystem corruption for the guest. Host is Windows 7, guest is Ubuntu 10.04 LTS. I first saw this with VirtualBox 4.1.16, but upgraded to 4.1.18 and saw it on it as well.
bitbake conf/local.conf has these lines
PARALLEL_MAKE = "-j4" BB_NUMBER_THREADS = "2"
It gives the possibility of running two make -j4 in parallel.
I found bug #10292 that seems to relate to heavy disk I/O, but I've not seen an assert so I create this new ticket instead.
