[PLUG] Lucid SSD issues (e.g. Mini9)
|
For anyone running an SSD, especially on a netbook like a Mini9, there
seems to be several issues going on.
https://bugs.launchpad.net/ubuntu/+source/libatasmart/+bug/445852
devkit-disks-probe-ata-smart causes HSM Violations on SSD, and potential
hardware death
[Really, really long, moved to bug 574462, see below]
Lucid fixed some cases:

https://bugs.launchpad.net/bugs/574462
udisks-probe-ata-smart causes HSM violations
[Pretty sure this one affects me on my Mini9]
Other/older:
HDA freezes (but recovers) under lucid beta on HP netbook
https://bugs.launchpad.net/ubuntu/+bug/555451
https://bugs.launchpad.net/ubuntu/+source/kernel-package/+bug/555787
ata loses interrupt, system freezes
I'm seeing stuff like the following at 37 minutes after every other
hour, mostly. See
https://bugs.launchpad.net/ubuntu/+source/hdparm/+bug/574462/comments/19.

"Microsoft Tax" = the additional hardware & yearly fees for the add-on
software required to protect Windows from its own poorly designed and
implemented self, while the overhead incidentally flattens Moore's Law.
