This still occurs after having flashed the TS-L632D to bios A01 (Acer,
from toshibaer's site), as well as having done a motherboard BIOS update
also.
I may have found a way to trigger this very quickly. I put in CD-RW media in
the drive, and launched Serpentine to burn a series of files to CD:
system nearly froze. Difficult to get a root shell, and needed to both kill
hald-addon-storage and reset the drive through hdparm.
Does anyone know how to decrease hal's polling interval ? This wold
help, until the issue is fixed in both the kernel & hal (I hope such
fixes will be bckported.)
Snips from dmesg, nothing new.
