I would concur 100% with everything Mouse has said in this thread, and add the following (with respect to partitioning): - asking if I want to use the existing partition table without first showing me what it contains, is more often than not worse than pointless. -- -- Greg A.

I removed a lot of those types of questions when I hacked at sysinst many years ago. Not sure if/why I left that one in, or it got added back later. My usual scheme was to display the current data with the cursor on the 'accept it' box - so typing <enter> would be enough. David -- -- David Laight: david <at> l8s.co.uk

only think i'm aware of is the "no_irq_affinity" quirk for E7520/7320/7525.
from their comment:
/* BIOS may enable hardware IRQ balancing for
* E7520/E7320/E7525(revision ID 0x9 and below)
* based platforms.
* Disable SW irqbalance/affinity on those platforms.
*/
can anyone test on those hardware?

I've got a Dual Core machine with an Intel E7230 chipset: HP ProLiant ML110 G4 (1.0) [...] pchb0: Intel E7230 Host (rev. 0xc0) But I would need a patch for "netbsd-5".

Hi, My name is Lena. I finded a few adress and writing you with despair from library of our small city. I recently losted my job and can not pay for heating our home anymore. My husband leaved me with my little daughter. We need heating is urgent because winter comes and the temperature in our home is very cold. For this purpose we need a wood-burn-stove, but we can not buy it because it costs too much for our family. If you have old, not great size and portable wood burn stove, I pray you can gift to us and departure it to our address. I await your response. I wish you a Merry Christmas and all the best in New Year. Lena. Russia.

I think it's the same as with -HEAD: just change:
#if 0
if (ci == NULL ||
ci->ci_nintrhand > lci->ci_nintrhand) {
ci = lci;
}

In my case it was non-working (lost) interrupts, I guess interrupt storms
could also happen.

Well, *that's* disappointing!(Continue reading)I don't have much idea how interrupts are routed. Is it possible that NetBSD needs to write some registers on the CPU/chipset to enable interrupt machinery on the application processors because the BIOS neglected to do so?
