This is a multi-part message in MIME format. ------=_NextPart_000_0124_01C48E03.8D80A180 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: quoted-printable Attached are two boot logs with sources as of today (Sunday 8/28/2004) = with both the standard GENERIC kernel configuration and the generic kernel modified to include a single additional device, the PUC device. The = system is a Dell GX300 Dual PIII/733 with PCI 3COM Ethernet, a 3COM internal = modem, and 29160 SCSI. =20 Basically, any PCI SIO device hogs its interrupt if the PUC device is = not also in the kernel, and this causes real problems for any environment = like mine where pulling the modem is not trivial. Does the distributed = GENERIC kernel have room for the PUC device? Are there side effects that PUC = should be excluded from GENERIC? As a bonus, there appears to be a bug with kernel locking exposed by the problem. With the stock generic kernel, the XL device reports it = couldn't map the interrupt, and then a lock order reversal is reported. (See the attached log for the gory details). Suggestions? The machine is pure test mode now. I can test either CVS updated source = or private patches. ------=_NextPart_000_0124_01C48E03.8D80A180 Content-Type: application/octet-stream; name="generic.log" Content-Transfer-Encoding: quoted-printable Content-Disposition: attachment; filename="generic.log" ahd@xena.hh.kew.com:/scratch/xena/obj/scratch/current/src/sys/GENERIC WARNING: WITNESS option enabled, expect reduced performance.
