LocutusOfBorgapw, we got probably the virtualbox kernel issue08:56
LocutusOfBorg>I haven't taken a look at the in-kernel version, but in RC1 the reason08:57
LocutusOfBorg>was that the arguments to out*() calls got swapped: the Linux kernel08:57
LocutusOfBorg>reverses them compared to everyone else I know of, and I failed to do08:57
LocutusOfBorg>that during clean-up to match kernel style.  Will be committing soon.08:57
apwLocutusOfBorg, wonderful08:57
apwwhen will we have updated packages for that to take form ?08:58
apwfrom ?08:58
LocutusOfBorgI already asked for a patch09:10
LocutusOfBorgbut if you have time, you can swap the parameters inside that outw call and see what happens09:11
LocutusOfBorgafter re-enabling it09:11
apwsforshee, ^^09:17
sforsheeLocutusOfBorg: I grepped the vboxguest code in our kernel tree, I only found out* being used in one file (include/VBox/VBoxVideoGuest.h). The arguments are reversed, but best I can tell they aren't compiled in, looks like ASMOutU* is called instead, for example12:15
sforshee#ifdef VBOX_XPDM_MINIPORT12:15
sforshee    VideoPortWritePortUchar((PUCHAR)Port, Value);12:15
sforshee#elif defined VBOX_GUESTR3XORGMOD12:15
sforshee    outb(Port, Value);12:15
sforshee#else  /** @todo make these explicit */12:15
sforshee    ASMOutU8(Port, Value);12:15
sforshee#endif12:15
tjaaltonwhat's the problem with vbox?12:16
tjaaltonsforshee: btw, when will next artful kernel be tagged?12:16
sforsheetjaalton: look at the code I pasted, the arguments to outb are reversed12:16
sforsheetjaalton: not sure, in theory the current artful-release kernel would be what we release with, so after release12:17
sforsheebut if we have any critical bugs we may do another before then12:18
tjaaltonthere was some wifi bug that the new stable release fixed12:18
sforshee4.13.5?12:19
LocutusOfBorgsforshee, I don't know honestly... I'll wait for the next vbox beta, and then see if at least vbox is fixed12:19
LocutusOfBorgin the meanwhile I hope somebody fixes the kernel too12:19
sforsheeLocutusOfBorg: are you talking about the vboxvideo staging driver?12:20
sforsheeI had to disable that in our kernel because it was causing problems12:20
LocutusOfBorgsforshee, yes, I'm talking about it12:21
LocutusOfBorgbut the current vbox beta has the same trouble12:21
LocutusOfBorgbecause the kernel driver has been merged back into vbox code12:21
tjaaltonsforshee: yep, 255432ecc6cbaf4 mac80211: fix deadlock in driver-managed RX BA session start12:21
LocutusOfBorgso, they "copied" the issue12:21
LocutusOfBorgand one issue discovered in vbox was that out* stuff12:22
LocutusOfBorgmaybe this is not enough, I don't know12:22
sforsheeLocutusOfBorg: okay. Thanks for the heads up, let us know when you have more information. But wrt to the mainline driver we won't have issues because it is disabled.12:23
sforsheemaybe that is why we had problems12:23
LocutusOfBorgsure I know it is disabled12:23
LocutusOfBorgand the driver in 5.1.28 is working12:23
LocutusOfBorgfact is: the mainline driver is broken12:23
LocutusOfBorgvbox 5.2 beta2 was still ok12:24
LocutusOfBorgin 5.2 rc1 they merged the mainline into vbox again, and they broke vbox bundled driver too12:24
LocutusOfBorgthey discovered such "swap" out function error, so maybe this is the problem in the kernel too12:24
sforsheetjaalton: how bad is that bug? Will it prevent users from installing or from updating after they install?12:24
LocutusOfBorgthis is what I know, the next RC of vbox 5.2 will have a "fixed" driver12:24
LocutusOfBorgso I'll do some more testing and then see what the mainline kernel driver misses, and maybe we can re-enable it12:25
tjaaltonsforshee: "Can't switch wireless connection between several WiFi APs"12:25
tjaaltonso not too bad I guess12:25
sforsheetjaalton: yeah from that description at least sounds like something that could be fixed after release12:26
gQuigsfrom the linux-firmware changelog (artful) it should include the latest iwlwifi firmware - but the files differ16:10
