+ alan: "Floppy has worked for me since the patches that went in 2.5.69-ac + and I think -bk somewhere" + + PRI1 + drivers/char/ ~~~~~~~~~~~~~
o Alan: Multiple serious bugs in the DRI drivers (most now with patches thankfully). "The badness I know about is almost entirely IRQ mishandling. DRI failing to mask PCI irqs on exit paths."

o IDE requires bio walking
"Bartlomiej has IDE multisector working" (does that mean it''''s fixed?)
+ PRI1
o IDE PIO has occasional unexplained PIO disk eating reports
+ PRI1 + o IDE has multiple zillions of races/hangs in 2.5 still
+ PRI1 + o IDE scsi needs rewriting
+ PRI2 + o IDE needs significant reworking to handle Simplex right
+ PRI2 + o IDE hotplug handling for 2.5 is completely broken still
+ PRI2 + o There are lots of other IDE bugs that wont go away until the taskfile stuff is included, the locking bugs that allow any user to hang the IDE layer in 2.5, and some other updates are forward ported. (esp. HPT372N).
+ PRI1 + drivers/isdn/ ~~~~~~~~~~~~~
(Kai, rmk)
o isdn_tty locking is completely broken (cli() and friends)
+ PRI2 + o fix lots of remaining bugs in the isdn link layer / hisax protocol layer / hisax subdrivers, so that at least 99% of the users have a usable ISDN subsystem
+ PRI1 + o fix other drivers
+ PRI2 + o lots more cleanups, adaption to recent APIs etc
+ PRI3 + o fixup tty-based ISDN drivers which provide TIOCM* ioctls (see my recent 3-set patch for serial stuff)
Alternatively, we could re-introduce the fallback to driver ioctl parsing for these if not enough drivers get updated.
+ PRI3 + drivers/net/ ~~~~~~~~~~~~
o davej: Either Wireless network drivers or PCMCIA broke somewhen. A configuration that worked fine under 2.4 doesn''''t receive any packets. Need to look into this more to make sure I don''''t have any misconfiguration that just ''''happened to work'''' under 2.4

o qlogic follies:
- jejb: Merge the feral driver. It covers all qlogic chips: 1020 all the way up to 23xxx. mjacob is promising a "major" rewrite which eliminates this as a candidate for immediate inclusion. Panics on my parisc hardware, works on my ia64. BK tree is @@ -866,81 +1041,193 @@ until I at least see how Qlogic responds to the issues. Can''''t currently build this for my only fibre card (a qla2100). BK tree is at http://linux-scsi.bkbits.net/scsi-qla2xxx-2.5
- I think the best plan currently is not to merge either of these, but keep shadow BK trees for them (thus holding out the possibility of merger) to see how they evolve. I agree with hch that feral seems to be in the better shape but, barring directions to the contrary, I can''''t see why both shouldn''''t be included eventually.
+ PRI2 + arch/i386/ ~~~~~~~~~~
o Also PC9800 merge needs finishing to the point we want for 2.6 (not all).
+ PRI3 + o ES7000 wants merging (now we are all happy with it). That shouldn''''t be a big problem.
+ PRI2 + o davej: PAT support (for mtrr exhaustion w/ AGP)
+ PRI2 + o 2.5.x won''''t boot on some 440GX
alan: Problem understood now, feasible fix in 2.4/2.4-ac. (440GX has two IRQ routers, we use the $PIR table with the PIIX, but the 440GX doesnt use the PIIX for its IRQ routing). Fall back to BIOS for 440GX works and Intel concurs.
+ PRI1 + o 2.5.x doesn''''t handle VIA APIC right yet.
1. We must write the PCI_INTERRUPT_LINE
2. We have quirk handlers that seem to trash it.
+ PRI1 + o ACPI needs the relax patches merging to work on lots of laptops
+ alan: ACPI relax stuff is in 2.4-ac, compaq workaround is in next -ac + coming. These seem to deliver the goods - toshibas now work a treat. Some + other relax bits are being discussed (assume local0 starts 0 etc) and + progress looks great. This can occur before 2.6 or during. + + PRI1 + o ECC driver questions are not yet sorted (DaveJ is working on this) (Dan Hollis)
+ alan: ECC - I have some test bits from Dan''''s stuff - they need no kernel + core changes for most platforms. That means we can treat it as a random + driver merge. + + PRI3 + +o alan: 2.4 has some fixes for tsc handling bugs. One where some bioses in + SMM mode mess up our toggle on the time high/low or mangle the counter and + one where a few chips need religious use of _p for timer access and we + don''''t do that. This is forward porting little bits of fixup. + + ACPI HZ stuff we can''''t trap - a lot of ACPI is implemented as outb''''s + triggering SMM traps + + PRI1 + arch/x86_64/ ~~~~~~~~~~~~

o time handling is broken. Need to move up 2.4 time.c code.
+ PRI1 + o Another report of a crash at shutdown on Simics with no iommu when all memory was used. Could be related to the one above.
+ PRI1 + o NMI watchdog seems to tick too fast
+ PRI2 + o not very well tested. probably more bugs lurking.
+ PRI1 + o need to coredump 64bit vsyscall code with dwarf2
+ PRI2 + o move 64bit signal trampolines into vsyscall code and add dwarf2 for it.
+ PRI1 + o describe kernel assembly with dwarf2 annotations for kgdb (currently waiting on some binutils changes for this)
+ PRI3 + arch/alpha/ ~~~~~~~~~~~
o rth: Ptrace writes are broken. This means we can''''t (reliably) set breakpoints or modify variables from gdb.
+ PRI1 + arch/arm/ ~~~~~~~~~
o rmk: missing raw keyboard translation tables for all ARM machines. Haven''''t even looked into this at all. This could be messy since there isn''''t an ARM architecture standard. I''''m presently hoping that it won''''t be an issue. If it does, I guess we''''ll see drivers/char/keyboard.c explode.

o SH/SH-64 need resyncing, as do some other ports. No impact on mainstream platforms hopefully.
+ PRI2 + o IA64 needs merging, has impact on core code
