> "I'm sure" meaning "I didn't test it" ? absolutely, I believed that the driver was *exactly* the same as the previous release which didn't boot and needed the fix, but another fix has been applied and corrected it. Now I think it will work with a clean 2.2.18pre25. Anyway, I left a kernel compile behind me this evening, so I'll confirm this on monday as soon as I can reboot the server on a pre25.

When I quickly sent you the last patch, I didn't notice that some other broken code had been removed, what I discovered later back home and after comparing 2.2.18pre2[15] (what Miquel noticed too). Next time, I'll spend a little more of my time on carefully reading the patch before resending an old useless one. Cheers, Willy ___ Do You Yahoo!? -- Pour dialoguer en direct avec vos amis, Yahoo!

Alan, I replied to you a few weeks ago (pre20 times) when you asked me why
I was sending you this patch. (perhaps you didn't receive my email). What I
observed was that my netraid card had a 0x8 base address and the patch
aligned that address to 16 bytes :
|Bus 0, device 2, function 1:
| Unknown class: Intel OEM MegaRAID Controller (rev 5).
|Medium devsel. Fast back-to-back capable. BIST capable. IRQ 10. Master
Capable. Latency=64.
|Prefetchable 32 bit memory at 0xf000 [0xf008].
as you see, the board is found at 0xf008, but used aligned to 0xf000.
my server currently works with that patch, but I'm sure it won't boot anymore
if I apply this 2.2.18pre25 alone.
just in case, here it is again.
Cheers,
Willy

Re: Linux 2.2.18pre25
Bad day, Alan? ;) Umm no but having people _keep_ sending you do nothing patches gets annoying after a while ;) Please accept all my apologies, Alan. When I quickly sent you the last patch, I didn't notice that some other broken code had been removed, what I discovered later back home and after comparing 2.2.18pre2[15] (what Miquel noticed too). Next time, I'll spend a little more of my time on carefully reading the patch before resending an old useless one. Cheers, Willy ___ Do You Yahoo!? -- Pour dialoguer en direct avec vos amis, Yahoo!

Re: Linux 2.2.18pre25
"I'm sure" meaning "I didn't test it" ? absolutely, I believed that the driver was *exactly* the same as the previous release which didn't boot and needed the fix, but another fix has been applied and corrected it. Now I think it will work with a clean 2.2.18pre25. Anyway, I left a kernel compile behind me this evening, so I'll confirm this on monday as soon as I can reboot the server on a pre25.

Re: Linux 2.2.18pre25
Well, I've found that VM-global patch before, of course. Until now, the last version was against pre18. Since I do not know the exact rules for including new things into Alan's tree, I thought that VM-global patch was already included in pre24. Sorry for my lack of experience. ;-)) I should have checked it. As I wrote before, I had no time recently to follow the mailing list carefully and I didn't know exactly what VM-global patch is. # It seems we need to return back to 2.2.13 for some time. :-( # Definitely no, you only need to apply the above collection of bugfixes. Ok, I can try it, at least. I will let you know about results. VM-global is currently on my 2.2.19pre pile of stuff.
