Well, if you look at the report you'd notice that:
- I'm using a released, stable, distro (Arch Linux, basically vanilla) kernel.
I hardly know how to compile one, let alone bisect it.
- I first had the problem on my 5+ year old Pentium 4 with equally old Intel
graphics (845G chipset). I thought it would be hardware specific. But now I got
a new Core 2 Duo with new Intel graphics (G45 chipset), moved to 64bit, and
still have the exact same problem and exact same workaround. So I really don't
believe anymore it's something hardware specific and should be quite general to
anyone using Intel graphics. I hoped someone with much better knowledge could
reproduce it and investigate it better.
On the report, Eric Anholt mentioned a likely cause and said that Jesse Barnes
had looked into a similar issue before. I cc'd him (jbarnes) on last week
reminder, but got no reply.
I really wish I could do more, but learning to compile a custom kernel for my
hardware and do a git bisect is something I just can't afford now. If relevant
people try to reproduce it but can't, and say only possible solution would be
for me to bisect it I guess I could try to give it a go when I get some spare
time.
Thanks,
Alberto.
