Re: Linux 2.4.5-ac2
actually, it happens on ext2, also. it was fun trying to switch back to 2.2 after converting raid devs for 2.4 and trashing my emergency boot disk. i was finally able to restore from tape by mounting -o sync. there was still some minor corruption caught by fsck, though. the new sym53c875 driver seems to have fixed the pci_map_sg() problem i was having, but now it complains about scsi script errors. changing the TCQ defaults from 32 to 8 fixes that. though, the corruption (even with TCQ max 8 and -o sync) may be related. anyone else tried 2.4.5-ac2 on a miata or other alpha?

2.4.5-ac17 swapoff machine check
i had about 50megs of swap "used" when i ran swapoff -a. that trigger two machine checks, but the box stayed up and seemed none the worse. here's the syslog.

There's no need for the government to restrict the rights of patents holders to sell all their rights, if they choose to. -- Tom Vier <[EMAIL PROTECTED]> DSA Key ID 0x15741ECE - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
pci_map_sg() failure on alpha
has anyone else had problems with pci_map_sg() in 2.4.4-ac*? i get the message from line 512 in pci_iommu.c, "pci_map_sg failed: could not allocate dma page tables" printed about 10 times, then a second or two later, it kills the interrupt handler. it's being called by the sym53c8xx driver. it's easily reproducible, by bunzip linux.tar.bz | tar x. this is on a pws 500ua, btw. -- Tom Vier <[EMAIL PROTECTED]> DSA Key id 0x27371A2C - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
